I had a slight question/concern with the following - 

-- Relational operators return false for false and a value other than
-- false/nil for true 

Although this solves the unmarshalling problem it doesnt solve the
marshalling problem for boolean values (it isnt possible to distinguish
a 'true' value as a boolean without explicitly casting it) 

For orthogonality I would be useful to also have a 'true' type such
that 

-- Relational operators return 'false' for false and 'true' for true 

Assuming 'true' was a non-nil value I dont believe this changes the
semantics of any relational operators
