So, you want to skip that extra func() call and have the code be
"inlined". That's one of the things what any decent optimizing compiler
does anyway.
I hear great things especially about ldc and that gdc is just good
enough. Of course, one needs to check the assembly output to be sure
that there is no extra function calls.
