I tried File::Slurp once, and found that it didn't take an argument for opening the file in binary mode. So I couldn't use it in the spot I planned it for! I included my own slurp function, called something like read_whole_file, in the program that did what I needed. This gives the benifit of it being more readable than the idiom, the ability to change it in once place only (after all, if they forgot binmode what else might go wrong some day?), and no hassle of installing a module.
