Since 'lazy void' is really shorthand for 'void delegate()' I wouldn't actually
have expected 'lazy' to work in this way anyhow...  Although it could indeed be
useful.  Try running it with 'tuple!(lazy void, lazy void) a' and it should
work.

I consider this an enhancement request, or clarification request, rather than a
bug.  (It'd be a nice enhancement, though.)
