There is some code that was obsolete several years ago.

You and Richard never seemed to understand this previously.

You may be half right.
https://en.wikipedia.org/wiki/Pure_function
Only the analyzer must be pure.
The input is free to get stuck in an infinite loop.

Inputs are not required to be pure functions.
