- Add p5-lexical-underscore 0.001 Starting with Perl 5.10, it is possible to create a lexical version of the Perl default variable $_. Certain Perl constructs like the given keyword automatically use a lexical $_ rather than the global $_. It is occasionallly useful for a sub to be able to access its caller's $_ variable regardless of whether it was lexical or not. The (_) sub prototype is the official way to do so, however there are sometimes disadvantages to this; in particular it can only appear as the final required argument in a prototype, and there is no way of the sub differentiating between an explicitly passed argument and $_. The lexical::underscore function returns a scalar reference to either a lexical $_ variable somewhere up the call stack (using PadWalker magic), or to the global $_ if there was no lexical version. Wrapping lexical::underscore in ${ ... } dereferences the scalar reference, allowing you to access (and even assign to) it.
