Thanks, it's helpful to consider the anonymous function literal version of
the `map` with `str/lower-case` function. I think that also highlights why
the first function in the `comp` doesn't use `partial` and instead uses
`#()', because of the position of the variable argument:
#(str/split % #"(?<=[a-z])(?=[A-Z])")
