I think one would also need to change the occurrence of the part after the
UnaryExpr:
-min occur zero- to fix parsing of simple unary expressions 
-max occur unbounded - to support chaining
So the EBNF should look sg. like:

[NN]    ArrowExpr ::= UnaryExpr ("=>" ArrowFunctionSpecifier ArgumentList)*
