I am not facile with Python. But my reading of these lines is that
they require strong typing, including bounds checked arrays and
strings, and disciplined object references (e.g. Java). Also, my
personal interpretation is that whatever the main body of code is
writen in, there cannot be a second level of interpretation, i.e.
Python and Java would be OK by me as primary languages even though
they are interpreted, as long as there were not another level of
interpretation of some other language. But, of course, I am not an ITA.

And if it were up to me these lines would seem to preclude C, because
of the confusion between integers and pointers in that language does
not allow any strong way of controlling pointer references; but I
doubt the ITAs interpret it that way, or enforce it.
