Add Peek
Add a peek function to let the Lexer look at a character arbitrarily
far ahead in the stream without consuming anything. We need this to
disambiguate numbers and operands of a paste operation. For example:
def foo#8i
Without lookahead the lexer will treat '8' as a number rather than as
part of a string to be pasted to form an identifier.
