what about something that catches mixin results into a static 
compiletime strings

template GenStruct(string Name, string M1)
{
     const char[] GenStruct = "struct " ~ Name ~ "{ int " ~ M1 ~ "; }";
}

which generates:

struct Foo { int bar; }

catch_generated_output(my_mixin_output)
{
   mixin(GenStruct!("Foo", "bar"));
}

pragma(msg, my_mixin_output);

prints:

struct Foo { int bar; }
