I changed hte "i" to "k".
Even though "i" was being used as a variable and not in its capacity as a built-in function.

In what order the names of the function are sorted?
(Thanks for the useful tags.)

The functions are sorted alphabetically and by type.
Ex. [built_in_alphabetical, toolkit_alphabetical]
