liblexical-underscore-perl 0.004-1 (arm64 binary) in ubuntu focal
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 $_.
