Isn't it using fromEnum/toEnum under the hood, which might have bigger<br>
performance penalty than `coerce`?<br>
<br>
On the other hand, sure, the original suggestion can also be made as a<br>
separate library wrapping IntMap/IntSet and all the calls to coerce.<br>
I'm happy with that approach too.<br>
