This is only used once. Worth defining?

Added this at the top for clarity in if condition, but yes since it is used only once, will rewrite this and move it with the calling condition.

rear_guard ?

The previous code entered deadlock since the last element inside the def was locked (not sure about the reason for this), so to avoid that, I replaced the read() function with try_read to prevent the blocking behavior.

Sounds like the code would then fail randomly instead of deadlocking, then?

From what I have tested, only the last element inside the class definitions was locked. I was unable to see what it corresponded to in the class, but methods including the constructor were already processed. I think avoiding deadlock here should be more important as the code after it can give more meaningful error messages. I will further look into the reason for this blocking and update here.

Please break it into another PR while you investigate it.
