This is a slightly different code golf from the usual problems. I'm forced to work with Java at my workplace and I'm increasingly annoyed at what I must do to read a file into memory to a String so I can operate on it in a normal way.
The golf is this: What is the shortest possible function to dump a file into your language's smallest data structure of characters?
Java would be char, C++ would be char*, Haskell would be a [Char], etc. I don't care about complete programs or main() functions, but you do have to open and close the file.
