No PLEASE!  This is the most bogus syntactical misfeature in Perl
after unquoted literals.  If anything, it should be:

	if (foo) blah;

The reversal is just plain hideously hard to wrap a programmer's brain
around.

This is, by the way, hideously inefficient and would cause severe
server spam, since you are needlessly creating a list when you don't
need to.  Perl gets around this by having a pretty extensive
optimizer, but developing one for MOO would be a *lot* of work.
