Nice, finally someone who actually wants to discern Exception
types. I'm always at a loss as to what warrants its own
exception type. E.g. when looking at network protocols, would
a 503 be a NetworkException, a HTTPException or a
HTTPInternalServerErrorException ?
Where do *you* wish libraries would differentiate?
Or does it really come down to categories like "illegal
argument", "division by zero", "null pointer", "out of memory"
for you?
