How would one explicitly allocate space for a closure? (That is, in such a way that one could handle allocation failure.) I can't find any examples nor any hints about what the syntax might look like.

Closures are stack allocated unless you wrap them in something like a Box, so it's up to you. They're no different than any other value.
