That is obviously fine, just don't decorate it with a memoization operator.
But don't code that is manifestly wrong with a memoziation operator but
then fixed by a subtle varia

IMHO we shouldn't slow down cached_method just to allow you to write
incorrect code (and caching a returned list is a bug). If anything,

Hi All,
I know it would considerably slow down @cached_method, but what about the
following:
- When a new item for the cache is first computed, test whether it is
hashable.
- Along with the item, store whether it is hashable or not (so that
there's no need to test hashability again).
- If an i

For efficiency, we might have a version of @cached_method which does
store a version of the output once it is computed, but does not directly
return what it's in store. Instead,
