uninit - Warn about uninitialized variables

SYNOPSIS

Top

    perl -Muninit myprogram

DESCRIPTION

Top

It's all very well being warned about the use of undef if you don't know what variable it is that contains undef, especially if you've got more than one variable in a line.

uninit attempts to do compile-time static checking of your program to see if any variables are used before they have any values assigned to them; it also reports which variable actually caused the problem.

It isn't guaranteed to catch all cases, and you can probably trick it with judicious use of eval, but I can't do anything about that. It's only a guideline.
