refactor: change onType to match and take only one pattern and result (#22)
Pursuant to #12. Besides changing the name of onType to match, and only allowing one pattern and result in `match()`,
this PR also arranges that in place of an onType with lots of alternating PATTERN, VALUE, PATTERN, VALUE arguments, one now exports an _array_ of `match(PATTERN, VALUE)` items.
Doesn't quite fully resolve #12, because there is still the question of whether `match(...)` can be left out for a behavior that literally matches anything (current behavior), or whether `match(Passthru, behavior)` should be required for such cases.
