[New-bugs-announce] [issue43892] Make match patterns explicit in the AST

[Nick Coghlan]

New submission from Nick Coghlan <ncoghlan at gmail.com>:

In the SC submission ticket for PEP 642 (https://github.com/python/steering-council/issues/43 ), Guido indicated he was in favour of the more explicit pattern matching AST changes suggested in that PEP.

This ticket covers adapting the pattern matching implementation to explicitly separate pattern nodes from expr nodes in the AST, so the code generator doesn't need to be context dependent.
