You probably refer to the fact that unreadable code can be created with it, right?
You've read me corrrectly.
Of course if you really want to write unreadable code you could always use what I cut my coding teeth on - APL
APL was once promoted as yet another "last language you'll ever need to learn." It used a bizarre set of symbols for commands, some of which were typed by backspacing and overstriking a previously typed symbol. (What further proof do we need that aliens are living among us?)http://en.wikipedia....programming_language
APL made several breakthroughs as a programming language. One of them was that you no longer had to wait a week before you had trouble remembering how your program worked. With APL, you forgot about 20 minutes after you wrote it.
Many times, if you found an error in an APL program, it was easier to write the whole thing over rather than try to edit it.
Here's an example:
The above is one of the clearer examples in that it is broken out line by line, and is commented. Most APL programmers did neither.
