Revisit the String template syntax

[Attila Kelemen]

I would certainly not change it:

1. This leaves the non-prefixed possibility as an option.
2. That would be a waste, because now you have to escape "$".
3. This would make some syntax difference between the two versions of
quotes, making conversion error prone.
4. Even though a lot of languages employ the "$" way, the "\{...}"
makes more sense conceptually, since you are kinda escaping an
expression.
