Hi Garry,
You either use inline operators ^ and !, or use a rewrite rule, not both. To
reference a rule, add a $ before its label:
mapType
: 'map' '<' k=anyType ',' v=anyType '>' -> ^('map' $k $v)
;
but I think this should work too:
mapType
: 'map' '<' anyType ',' anyType '>' -> ^('map' anyType anyType)
;
Regards,
Bart.
