Another strange question, this time to do with extended precision numbers.

Have you ever wanted good performance out of a large array of 
extended-precision integers (or, for that matter, rationals), where most of 
the integers involved would not have fit in a machine integer (magnitude 
approx. 2^63)?

(I recognise that this is probably not an ideal place to ask, given that j's 
extended integers have not historically been even remotely performant.  But 
most things that aren't j have poor support for arrays, sooo~)
