    Name three general purpose programming languages without significant whitespace.

      For some reason my reply didn't post. There are many languages where whitespace is quite liberal and not taken to new heights of infamy like python, including C.


        It's funny you mention Perl. I assume you meant Perl 5. I have toke.c open right here. You might find the *SPACE macros illuminating. They're used in functions to disambiguate lexing of, for example, unary functions, non-predeclared barewords, line number detection, unary operators (a comment there gives an example of rand +5), version numbers, method calls, use invocations, shebang line parsing, line number detection in string eval constructs, the unary minus operator, the various occurrences of the > token, and I'm only a third of the way through the file.

        Can you be more specific than "I don't like Python's indentation, therefore any language with whitespace rules sucks?"
