The "variable" in a Perl for loop is aliased to each element that is being iterated over. It is effectively a symbolic place holder that is only valid within the scope of the loop body. However strict requires that variables are declared. Declaring the variable before the loop header makes it look like a normal variable - it ain't.

Perl's payment curve coincides with its learning curve.
