mixin.pm seems to tickle a change between the value of a constant subroutine on the symbol table. With constant.pm 1.13 & 1.15 perl5.10.0 -wle 'use constant FOO => "bar"; print $main::{FOO}' SCALAR(0x181dce0) With constant.pm 1.15 perl5.8.8 -wle 'use constant FOO => "bar"; print $main::{FOO}' *main::FOO This changes breaks the following code in mixin.pm. local *glob; while( my($sym, $glob) = each %{$mixin.'::'}) { next if $sym =~ /^_/; next unless defined $glob; *glob = $glob; # XXX AT THIS LINE *{$pkg.'::'.$sym} = *glob{CODE} if *glob{CODE}; } I don't know if it's a bug or not, but it's kind of weird to find a scalar ref on the symbol table. -- 91.
