Good point -- you scored a direct hit on the Smalltalk-homage
battleship here, IMHO.

In that case, you have to rewrite the grammar from:
OptionalParameter ::= Parameter '=' NonAssignmentExpression[allowIn]
to
OptionalParameter ::= Parameter '='
NonAssignmentExpression[allowIn,noOR]
Make it necessary complicated.
In feature(ES4), ES may have OptionalParameter, that will cause
trouble
{ |a ,b = 1 | c | d | e | f }
is
{ (|a ,b = 1 |) c | d | e | f }
or
{ (|a ,b = 1 | c) | d | e | f }

That should be a syntax error. Parenthesis should be required in that
case to avoid ambiguity: {|a, b = (1 | c)| ... }
