A while back I'd talked to Randal about closures, and he told me that a closure needn't be a code reference:
>>>>> "Jeff" == Jeff Pinyan <jeffp@crusoe.net> writes: Jeff> A closure is an ANONYMOUS function (constructed via $x = sub { Jeff> ... }) that contains LEXICAL variables that have been defined in Jeff> a scope visible to the closure itself. leave out the word ANONYMOUS there. ANONYMOUS and CLOSURE are orthogonal. in "BEGIN { my $x; sub foo { ... $x ... } }", foo is a CLOSURE and is not ANONYMOUS.
