The idea here is that an integer literal *can be typed as* a type that conforms to this protocol (the type suffix *is not* used in the sense that it used to be used in things like `SequenceType` which had the semantic that conforming types *are* sequences).  

Throwing my hat in:

IntegerLiteralCandidate (with or without a Syntax. prefix)

As in, when you see an integer literal and need to infer its actual type, this type is a candidate.
