is not in core and will only work with Perl version 5.005+
seems to have issues with Unicode files as well as several unadressed bug reports
does not help with any platform issues
usage is just plain unintuitive for a maintenance programmer in this case
I'm not trying to knock File::Slurp, it's probably good at what it does (though the numerous, long-running bug reports would give me pause), but what possible reason (other than obfuscation) would you have for using it in this case?
