capturex from core module IPC::System::Simple would be a simpler replacement for backticks.

      IPC::System::Simple is used by use autodie qw( system );, so it's bundled with Perl since autodie's creation in 5.10.1, and I suspect it was written for it.

        Turns out IPC::System::Simple ISN'T a core modure, even though it's used by core module autodie. use autodie qw( system ); fails if IPC::System::Simple isn't installed. 

        $ perl -e'use autodie qw( system );'
IPC::System::Simple required for Fatalised/autodying system() at -e li
+ne 1
BEGIN failed--compilation aborted at -e line 1.

        That's why use autodie; aka use autodie qw( :default ); doesn't include use autodie qw( system );.

        That's a huge wtf, especially considering the usefulness of what the module provides: It provides alternatives to questionably-designed builtin functions.
