I was hoping to avoid that, but apparently there's no way.
There are cases where this can be avoided, like calling pure
functions. Another win for pure functions!
It seems like the most common use case for passing a global to a
parameter is to process that global in a pure way. You already
have access to it in an impure function, so you could just access
it directly. The good news is that from within the passed-to
function, no further calls will treat it as global.
