I don't disagree with it. But the solution is really easy, just call 'sh' and pass it a string!

>>> from extproc import sh
>>> n = int(sh(“ls /etc –1 | wc –l”))

No parser needed written!

Yes there is a danger of argument parsing and globs and all that. But people are aware of it. With string parsing, ambiguity is always there. Even when you have a BNF grammar, people easily make mistakes.
