CachedAttribute

An attribute of a node type T with value of type U, supported by a memo table and circularity test. The value of the attribute is computed by the function f. The result is memoised so that it is only evaluated once. f should not itself require the value of this attribute. If it does, a circularity error is reported by throwing an IllegalStateException.

Has the value of this attribute at t already been computed or not? If the table contains Some (u) then we've computed it and the value was u. If the memo table contains None we are in the middle of computing it. Otherwise the memo table contains no entry for t.
