Why the complicated sig? Note that the left sequential definition enforces that ($a + $b) + $c dispatches to a version of + with the return type of the lhs addition. That is you need lots of overloaded versions of listfix +. Nonetheless I would like to define + and * to be listfix and commutative, that is independent of order. Note that this is orthogonal to the definition of evaluation order. Regards, TSa.
