$"{a} times 3 is {a*3}"
could be rewritten by the parser to:
"%s times 3 is %s", a, a * 3
and that is that. (I.e. just an AST rewrite.) It would be quite
a bit simpler than Jonas' proposed implementation.
For, say, sql query generator it would be nice to have a rewrite
like
sql!"select name from users where id={n}"
=>
auto q=query("select name from users where id=@p0");
q.addParameter("p0",n);
pragma(autoMixin)
template sql(string txt)
{
enum string sql=generateCode(txt);
}
If this can be rewritten as automatic string mixin like so:
sql!"select name from users where id={n}"
=>
mixin(sql!"select name from users where id={n}")
