Re^4: Variable Name Mistery. Who calls?

It's almost there. this is the output I've got: ~$ perl p.pl This will work This will work as well Couldn't execute three at p.pl line 9 And, what I want to achieve is to print (for example) which variable raised that warning. Something like this: Couldn't execute three on $o at p.pl line 9 Perhaps am I asking to much?

Well, you could use PadWalker's `var_name`. `var_name` won't always work, though. Before using PadWalker, ask yourself if you really think the tiny bit of extra usefulness to help debug the rare situation where a non-existant function is called more than once in a given statement is really worth the extra work, complexity and maintenance issues of displaying the variable's name (when there might not even be one).
