A bit of advice I think I read in The Elements of Programming Style:
try to make complex conjunctions look like their mathematical
equivalents, and they'll be easier to read. The mathematical way to
write the test above would be Start < MapInfo < End, so the programmatic
way to write it should be
Start < MapInfo & MapInfo < End
This makes the character of the interval completely obvious.
