in thread What magic is this?

That code block in my Expat.pm (version 2.34) looks like

if (defined $arg) { if (ref($arg) and UNIVERSAL::isa($arg, 'IO::Handle')) { $ioref = $arg; } elsif (tied($arg)) { my $class = ref($arg); no strict 'refs'; $ioref = $arg if defined &{"${class}::TIEHANDLE"}; } else { require IO::Handle; eval { no strict 'refs'; $ioref = *{$arg}{IO} if defined *{$arg}; }; undef $@; } }

but to me it looks equally scary. undef $@ after eval? wtf?

At least, there's no strict 'refs'; inside the eval (but isn't it another wtf?)

--shmem

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
