<p class="MsoNormal"><span lang="EN-US">Hi experts<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I thought I’d give my 2 cents here for a sec.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I just looked through this long email chain. I was busy with other things in life so I haven’t checked it out earlier.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">First of all, I was surprised it took so long for someone to only apply implicit conversion between `String` and `StringTemplate` only for constant `String`s given that there is already a similar case in the compiler.
`int`s can’t be implicitly cast to a `byte`, except (some) constant `int` expressions **<b>can</b>** be implicitly converted to `byte`.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This is by far my favorite suggestion posted so far (and if weren’t suggested yet, I would have). So I’m a bit surprised it seems to have disappeared again.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">On another idea going around, using a `$` prefix for string templates and having implicit `String.of(…)` on the “template” if it isn’t there is at the bottom of my list.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The fact that forgetting the `$` prefix just opens you up to an SQL injection attack, while the feature is being advertised as “safe” is for me unacceptable.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">(I’m not a big fan of `TEMPLATE"Foo: \{bar}"` either as it’s just so much longer than `"Foo: " + bar`)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I haven’t seen anyone suggesting the opposite though? Have a `$` prefix for standard String interpolation (for those apis that don’t accept a String) and when it’s not there it’s a normal `StringTemplate`. Adding an extra
char by accident feels much less likely to me than forgetting one. But I wouldn’t be against having it be something like `STR"..."` instead of `$"..."`.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Combining these would give the following:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">```<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">String s1 = "test" // still a string literal<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">StringTemplate st2 = "test" // allowed, constant strings can be implicitly converted to templates<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">StringTemplate st3 = "Foo: \{bar}" // Simple string template<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">// either<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">String s4a = $"Foo: \{bar}" // short for String.of("Foo: \{bar}")</span><span lang="en-BE"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">String s4b = STR"Foo: \{bar}" // short for String.of("Foo: \{bar}")<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">```<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Kind regards<o:p></o:p></span></p>
