Subject: [PATCH] H_VALIDATE_APPLY macro
I've found this especially useful in combination with my own
_attr_uint_const for things like flags and type specifiers.
It's possible that its usefulness might be diminished significantly if
there were a built-in bitfield constant parser -- that certainly would
eliminate all of my current uses of it -- but it still seems nicely
symmetric with H_ACT_APPLY.
