Even better:

mixin template generate(T) {
     T bla;
}

void main() {
     mixin generate!int;
     bla = 5;
}

String mixins, like inline assembly, is a very powerful tool. 
Just like inline assembly though, it's usually not the tool you 
should be reaching for. Generally, if it's possible to do 
something without string mixins, that way will be less error 
prone and more readable.
