Grammer for Map and List is incorrect

[TotallyNotChase]

The syntax grammer notes-

Data ::= "data" ( Sigma | List | Map | Integer | ByteString )

List ::= "[" Data* "]"

Map ::= "{" ( Data "=" Data )* "}"

Which suggests that { data 1 = data 5 } would be a valid Map, and [ data 1 ] would be a valid List. However, the parser doesn't actually expect the data keyword, it just expects the data literal.

If the parse behavior is intentional, then the grammer needs to be updated. If the grammer is correct, then the parse behavior should be updated.
