Neither does the string module work on binaries, which I've found
inconvenient. Fortunately you can just use an alternative
function/module.

Sometimes I have to write my own function, which is also inconvenient.

Modifying built-in type behavior (the vaunted Ruby string, but also
Python, etc.) is super extremely inconvenient.
