Example with 3 matchers: A, B, C
|

|
|
Match evaluates them: F, T, <?> => T
|
|
So match is currently T, what should MatchMayChangeInTheFuture() return?
|
|
Seems like it only depends on B, since currently B MUST change to allow the result to become F
|

Match eval: F, F, F => F

So match is currently F, what should MatchMayChangeInTheFuture() return?
|

Seems to depend on ANY of them being able to change to T.
