C would be another, although they're not called "modules". E.g. try
adding

ssize_t write(int fd, const void *buf, size_t count)
{
    return -1;
}

to your main C source file... :)

In document formatting troff was another - you could redefine/override
variables and macros.

However, in both C and troff, once you've overwritten a definition it's
rather hard to get to the original, unless you saved a reference to it
somehow.
