Yep, that's about the size of it. Want some examples of what costs no
clarity to reimplement in another language? Check out the Python
standard library. Some of that is implemented in C (in CPython) and
some in Python, and you can't tell and needn't care which. Code
clarity isn't hurt, because those functions would be named functions
even without.
