But not on all code.  Comments can obscure code, and code can too.
Here's a snip from the docs:

        # p2cwrite   ---stdin--->  p2cread
        # c2pread    <--stdout---  c2pwrite
        # errread    <--stderr---  errwrite

Is c2pread more or less obscure than c2pr or chi2parread?  If there's
an objective metric of the degree of something's obscurity (obscured-
ity), then that has an answer.  Is it a scalar, or if not, is there
abs( answer )?  Does that comment obscure the later code?  Are 'in'
and 'out' more or less obscure than those?

        (p2cread, p2cwrite,
         c2pread, c2pwrite,
         errread, errwrite) = self._get_handles(stdin, stdout, stderr)

Information design can get (*subjective) breathtaking, but if you see
a potential improvement, you should always be able to make it.

Tell me what you think of this simile:  Sometimes Steve Chessmaster
reads board positions, sometimes prose.  Some of the prose is less
obscure, -to- -him-, than board states.  To someone with a different
speciality, as in bishops vs. knights, endgame vs. openings, certain
forks, the states are less obscure than the corresponding prose.  To
my fmr. A.I. professor, "The minimax A*," and "The beaten path A*" are
plenty clear.  He can say what they do.  Can you?

But you're still calling it?

What if the word is generic?  Do you know if it has a return value?
