First off, this is very cool. I'd figure out a name for this and throw it onto CPAN.

A few thoughts:

The old-timey calling convention with "&" sigil and no parens is intended. Both subs are to be called with the same arguments, so it is convenient to not alter @_ in the base functions and have the arguments brought in automatically.
This doesn't work as you'd expect for functions that consume parts of @_, particularly with shift. I would make a two shallow copies of @_ and pass one into each of the subroutines. I think that would DWIM better.
You have conjunction of return values, disjunction of return values, and negation of return value. I would propose that you add composition - f( g( x ) ) - as well. While the first three are good, I can definitely see a need for the fourth. Unfortunately, I'm not quite sure what operation to overload for this. Maybe the bitshift operators? (f << g)(x) means f ( g(x) )? I dunno ...

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
