Write a checker (or two)

[krisajenkins]

It wouldn't be hard to write a checker that:

a) Checks all the functions we've listed actually exist (and are under the right namespace).
b) Discovers which core functions we haven't listed.

[krisajenkins]

(a) is done. We now check all the symbols exist. Just (b) to consider.

Done. :-)
