[DGD] lambda operator re-re-visited?

[Carter Cheng]

Actually I do not see it as that heuristical once the discriminant is added
the identifier is unique. Also basically programs are identified by file
name in the common case already. So you would have something like
filename#line number.discriminant for a given program and any object would
include the additional object number.. The discriminant is to differentiate
between two "closures" originating from the same line.
