I've being working with the grammar but I found somethinf difficult to
workarround. Can this be implemented with PLY yacc?
query ::= type_name ([query] )
query ::= type_name (identifier:query {, identifier: query})
query ::= struct (identifier: query {, identifier: query})
query ::= set ([query {, query}])
query ::= bag ([query {,query}])
query ::= list ([query {,query}])
query ::= (query, query {, query})
query ::=[ list](query .. query)
query ::= array ([query {,query}])
Thanks
