There are a fixed number of them -- though it's somewhere in the
thousands range... The array module would handle them quite nicely if
it supported 3-byte integers; but in general, a more generic struct
module will be handier than a more generic array module (I've never
dealt with a tuple with thousands of entries before -- is it likely to
be a problem? Anyway, wrapping it in a function to read all the ints
in blocks and put them in a list is very little trouble).
