Your code will not work if $_ is lexical. And I don't know whether that can be fixed. At first I thought you could solve it with a prototype: 
sub lchompx (;$_)

(swapping the arguments if two arguments are given). But will it gives you access to a lexical $_ is called with one argument, it won't pass $_ if not called with any arguments. A prototype of _;$ will fail to do right thing if one argument is given.
