The only way to declare a lexical variable outside a block for use only
inside the block is to declare it as a formal parameter via C<sub> or
C<< -> >> Inside the block you use C<my> as usual. However, you can
always increment such a variable:
while 1 {
my $i; FIRST { $i = 0 }; NEXT { $i++ }
}
Hmm, maybe we do need a FIRST to go with the LAST...

That would be the first time parens ever indicated that sort of thing
in Perl. And I'd rather not overload the meaning of parens any more
than it already is.
