due to encountering some compile errors on a fresh system which pulled
down the newest minor versions of both. these two libraries do not seem
to follow "good" semantic versioning ... ? ugh. will try to work out
the compiler issues with the latest versions of these later ...
i think i prefer this style. it's not _technically_ as safe as it was
before, but i prefer the explicitness of it (and it results in a little
bit less nesting in system functions which is nice).
i don't much like the need for an explicit `unwrap()` call however
but that's the tradeoff!
