This code:
#!/usr/bin/perl + use warnings; use strict; + use Symbol; + our $f1; $f1 = gensym; tie *$f1, 'TieTest'; <$f1>; + package TieTest; + sub TIEHANDLE { my $class = shift; my $obj = { }; bless $obj, $class; warn "TIEHANDLE: $obj\n"; $obj; } + sub READLINE { warn "READLINE\n"; return "line\n"; }
Produces:
TIEHANDLE: TieTest=HASH(0x80fcb38)
Use of uninitialized value in <HANDLE> at tietest.pl line 11.
readline() on unopened filehandle at tietest.pl line 11.
