C has well-defined error handling for when built-in functions are called
with bad input.  There is no such definition at the moment for HTML
(outside of WA1)/

Also, C code often has to fallback to the lowest common denominator: if
you want to use (for example) the `inline` keyword on a wide variety of
compilers, you need to have fallback for implementations which do not
have that keyword.  Backwards compatibility is a big concern unless you
control all aspects of the system your code will compile and run on.

I think this might be stretching the analogy a bit, but I think it was
stretched to begin with.
