I almost have the wrap - the builtin-type wrapper I provided won't quite
work "as is" because __float128 isn't a first class native type. But it's
only a cut and paste job to fix it up.

Might actually be too small for that, although it could be used as a way of
getting them started. Proabably not very "exciting" for them either :-(
