From Symbol::Approx::Sub docs:

This is _really_ stupid. This module allows you to call subroutines by _approximate_ names. Why you would ever want to do this is a complete mystery to me. It was written as an experiment to see how well I understood typeglobs and AUTOLOADing.

To use it, simply include the line:

  use Symbol::Approx::Sub;
[download]

somewhere in your program. Then each time you call a subroutine that doesn't exist in the the current package Perl will search for a subroutine with approximately the same name.

Is this going to be forgiving enough? :-)
