An important part of a programming language is that people can understand it.

I suspect it isn't hard to design a language that computers can easily
parse, but people can't.  Your lexer only needs to be good enough for
actual programming languages.

As with BBQs, that doesn't stop people from trying.
[Take a look at Postscript, which is trivial to tokenize and parse since
it's a stream of tokens in RPN order, but making sense of it
by humans is a challenge.  Or, of course, m4.  -John]
