I don't use File::Slurp ever (but without the uppercase and the punctuation :-)

Leon's blog post explains (some of) the problems with File::Slurp and at the end offers three alternatives. I tend to use Path::Tiny in preference because it isn't overkill, is already widely used and does just about anything I am likely to want in regards to files and directories, including slurping and spewing. YMMV.

I should also say that for published code which only slurps one single file I would probably just do that without a module as the overhead isn't really worth it in terms of efficiency and maintenance.
