that's puzzling.  I do lots of graphics, and some web programming (my
company's main product is a web application server for graphics), and
we use doctest for everything.

I find it a bit odd that someone thinks that there are tests for which

    assert something == somevalue

is easier to write than either

    >>> something
    somevalue

or

    >>> something == somevalue
    True
