Well, this is just a small piece of the puzzle but I would like to be
able to write (as syntax sugar):

query q{
  select data;
}

a compiler to rewrite it to:

mixin(query!(q{
  select data;
}));

if the following exists:

mixin statement query (string code) {
  // ...
}

Maybe I am the only one but I found that string mixins + code generation
are used this way even i Phobos and I find the first syntax much more
cleaner.

Or this is not in the general interest?
