The fp.read method takes a variable number of args, like the C printf.
That's ok, but I would think in an OO language, there would be seperate
methods for reading a set number of chars and for reading until EOF.
Maybe readEOF may call readBytes in it's implementation, but that is hidden.
(I've been influenced by Smalltalk, as you may have guessed.)
