SymbolPairs

abstract class SymbolPairs extends AnyRef

An abstraction for considering symbol pairs. One of the greatest sources of compiler bugs is that symbols can trivially lose their prefixes and turn into some completely different type with the smallest of errors. It is the exception not the rule that type comparisons are done correctly.

This offers a small step toward coherence with two abstractions which come up over and over again:

RelativeTo: operations relative to a prefix SymbolPair: two symbols being related somehow, plus the class in which the relation is being performed

This is only a start, but it is a start.
