As for the criticism that a later programmer might not understand the code: limiting yourself to widely-known and well-used syntax is the antithesis of Perl programming and I want no part of it.
But using obscure syntax when obvious and well-known syntax (a subroutine call) exists is the antithesis of maintainable code. There are so many ways to do things in Perl that you have to choose what you want to optimize for. Ovid says he wants to optimize for clarity and maintainability. That sometimes means doing things in a simpler way and avoiding cool but obscure (though documented) tricks like this.
