in thread Mysterious append failure.

Ahh.. that looks like it makes sense. Was forgetting for a minute that declaring $b there would actually scope it inside the loop.

D'oh.

    This isn't quite true - the output of Deparse is wrong. The lexical is scoped wider than the loop, as can be seen here:
    $ perl585 -le '$x=99; my $x = $_ for 1..3; print $x' $
    (Note that $::x isn't printed, the lexical $x is instead.) However, the initialising and releasing of $x is scoped to within the loop.

    That may be construed as a bug. There again, statement modifiers on my declarations are usally buggy, and are best avoided.
