Another advantage of Builder is that it's more flexible,
For example assume:
   T1 v1 = #{3, 4, 5}                    // list/collection
   T2 v2 = #[\(reg *\)exp]               // regular expression
   T3 v3 = #[10m^2/s]                    // quantity
   T4 v4 = #[The result is: ]{result}    // hybrid

The latter could be compiled into:
   T4 v4 = T4.builder()
             .addText("The result is: ")
             .add(result)
             .build();

If we have a map/pair syntax, an entry could be compiled
to a call to addEntry(key, value).

In addition addAll is useful for translating a "splice"
operator.
