Inline the wrapper?

[ceztko]

I talked about this idea also in sindresorhus/ExceptionCatcher#8 (if I'm not wrong the two projects seem quite similar in scope): could the Swift component function be marked inline so there are more changes the wrapper will be optimized?

I'll have a look over the weekend. I think I'd looked into this at one point and ran into issues but that was a few versions of Swift ago and things may have changed.
