I have code like this: 

if ($foo eq "true") { ...

[download]

This does what I want. If $foo is "true", it runs. If it's anything else, or not set at all, it doesn't. But -w throws warnings at me if $foo isn't defined. To satisfy it, I have to do this instead: 

if ($foo && $foo eq "true") { ...

The first check will short-circuit if it fails, so the warning doesn't get thrown. But it seems like I'm making my ifs unnecessarily complex. Is there a better/prettier way?

A fair fight is a sign of poor planning.
