Cannot assign from keywords about guacamole HOT 2 CLOSED

This is caused because the rule for OpListKeywordExpr (which includes keywords like open, chmod, splice) appears before the ExprAssign so they can't be matched.

I tried different ways of repeating this rule in the table after the ExprAssign. I was able to get these tests to work, but then stuff like while ( my ( $foo, $bar ) = splice @foo, 0, 2 ) {1} would get 3 different types of parsing outputs. :/

Right, we need to somehow allow OpListKeywordExpr as an RHS for assignment. This creates a loop in our precedence rules (ExprKwList -> ExprComma -> ExprKwAssign -> ExprAssign -> OpListKeywordExpr -> OpKwList), which creates an ambiguity: ($x = kw $y, $z) can be parsed as either (($x = kw $y), $z) or ($x = (kw ($y, $z))).

I don't know the solution to this yet.
