The error message is kind of unfortunate. This is a simple
usecase and the error message is undecipherable already. It'd
be cool if the compiler could try to strip immutability, and if
the type matches then, throw an error something like "Cannot
pass immutable char[] to reverse, did you mean char[]?".
That would help a lot, as I got "rikki cattermole"'s answer at
once, when my eyes were brought to the "immutable" part.
I come from the lisp world, so I'm kind of familiar with the idea
of copying and/or modifying in place to limit consing. I guess I
should I have realised this would be a perfect example of that
kind of situation.
