SetOrMapLiteral class abstract final

A set or map literal.

setOrMapLiteral ::= 'const'? TypeArgumentList? '{' elements? '}'

elements ::= CollectionElement ( ',' CollectionElement )* ','?

This is the class that is used to represent either a map or set literal when either the 'control-flow-collections' or 'spread-collections' experiments are enabled. If neither of those experiments are enabled, then MapLiteral is used to represent a map literal and SetLiteral is used for set literals.
