I haven't gone through the list exhaustively but I'm fairly certain it
will make a positive difference for the t-distribution and the
standard normal, especially since these are used in statistical tests
where people care about their p-values.
I just committed a fix for these two distributions, we can weigh the
worth of subclassing or not further (incidentally, this breaks two
ttest tests because they differ in the 17th decimal place, how sure
are you of those hard-coded numbers?).
