[issue21992] New AST node Else() should be introduced

[Mark Shannon]

Mark Shannon added the comment:

I would say yes, it is too late. Any change to the AST is a breaking change.

The current AST is full of missing line numbers, incorrect column offsets and other inconsistencies. To fix them all would be a major undertaking with no obvious benefit to the core interpreter.

If you are interested in implementing a parser with proper location information, I would suggest discussing it on the code-quality mailing list:
