Well, I think if the world had never seen all the bad
side-effects from 'C macros', most people would wholeheartedly
embrace mixin's today... since it cleanly avoids 'x' number of
design pitfalls from #define.

For maintenance, performance, portability considerations I
definitely prefer mixin's over reimplementing alloca for every
current and future targets/calling conventions.
