assume I have a small grammar like:
A: B / C .
When I try:
RULE: A ::= B COMPUTE
A.Type = B.Type;
(Assume that both A and B have Type attributes and B.Type is something
I get an error like "miscomputation of A.Type" from eli system.
Why does eli demand me to also add the rule(since adding this solves
RULE: A ::= C COMPUTE
A.Type = C.Type;
I couldn't understand the point. I would be pleased if someone explains.
