splinky has asked for the wisdom of the Perl Monks concerning the following question:
Ok, I have a package named Bob that looks like this:
And I use it in a program like so:package Bob; my $thingy = {One => 1, Two => 2}; sub doit { my $key = '{One}'; eval "print \"thingy one is \$thingy->$key\n\""; #my $x = $thingy; } 1;
I get the following when I run the program:#!/usr/local/bin/perl use strict; use warnings; use Bob; Bob->doit();
However, if I uncomment the "my $x" line in Bob.pm, it works fine:Use of uninitialized value in concatenation (.) or string at (eval 1) +line 1. thingy one is
I'm assuming this is a bug in perl. Is it fixed in 5.8.8?thingy one is 1
I'm running perl 5.8.6 under Linux (FC4).
Thanks!
