What is the point of a new exception? When would you ever want to
catch it as opposed to a regular SyntaxError? You're going to have to
change the code either way.

Moreover, all Python implementations are going to have to place some
limits on stack depth and recursion, so it's not really an
implementation detail.

The Python language doesn't make an mention of limited memory, but no
one is going to suggest a MemoryLimitError, which is an
"implementation detail".
