This whole thing is probably best implemented as two separate functions
rather than using a closure, depending on how intertwined the code paths
for the shortcut/non-shortcut versions.
I like the closure because it has semantic ownership: the inner function is a worker for the outer function.
True, a closure has better encapsulation, making it less likely someone will misuse the helper function. On the other hand, that means there's less modularity and it would be difficult for someone to use the inner function. It's hard to know the right choice without seeing the exact problem the original author was working on.

I'd flip the rare-case to the except block and put the normal-case in the try block. I believe this will be more compute-efficient and more
The rare case is in the except block, though.
You're correct. Sorry, I somehow misinterpreted the comment, "# To trigger the exception the first time" as indicating that code path would run only once.
