Thanks for the post Luke. I'd seen what Larry wrote, but for some
reason it didn't click until you wrote this. I think part of that is
because I was thinking of generators something like this:
sub foo :generator { while $cond { ... yield $foo; } }
@list = &foo;
Where the declaration and use were separate (in my fantasy here,
assigning a coderef to a list makes lazy eval happen). What was
throwing my brain I think it that gather is a declaration and "call"
all rolled into one.

That makes much more sense the synapse firing that was previously
happening in my head :-)

I would expect it to be the value of the last statement executed.
