if there's a core module that already takes care of such tasks

Not core, but I use File::Which. It correctly handles some of the eccentricities of various operating systems, like correctly handling implied extensions like .bat or .exe on Windows systems. With this module, the same line of code which("perl") will correctly find my Strawberry perl.exe on Windows or /usr/bin/perl on Linux.
