You're absolutely right. Any real language should catch these types of
errors, just as it would verify that the program below is correct:


if (aCondition):
    AFunctionThatIsDefined()
.
.
.
.
def AFunctionThatIsDefined():
    return 0 / (0-0)


Moral: There are *many* more reasons for testing every execution path
than catching name or type errors.
