This module provides a type that represents a pattern for a given match branch. See PEP 622.
type ('constant, 'expr, 'identifier, 'location, 'pattern) t = private {match_value : location:'location -> value:'expr -> 'pattern;Represent a pattern that matches constants, except None, True, and False literal.
match_singleton : location:'location -> value:'constant -> 'pattern;Represent a pattern that matches None, True, and False (i.e. literals that are compared by identity instead of equality).
match_sequence : location:'location -> patterns:'pattern list -> 'pattern;Represent a pattern that matches a sequence of other patterns.
*)match_mapping : location:'location ->
keys:'expr list ->
patterns:'pattern list ->

'pattern;Represent a pattern that matches a map of patterns.
*)match_class : location:'location ->

patterns:'pattern list ->

kwd_patterns:'pattern list ->
'pattern;Represent a pattern that destructuring arbitrary objects.

match_as : location:'location ->

'pattern;Represent a capture or wildcard pattern (e.g. case x as y, case x, or case _).
match_or : location:'location -> patterns:'pattern list -> 'pattern;Represent a pattern that matches a combination of other patterns.
