Hi,
This command is surprisingly slow,

This stems from the quirk I mentioned in an earlier email today.
The problem is that f.variables() relies on the

Sure.

Thanks Minh.
You're right about the transformation--it should read 'b' rather than
'a'. I'll fix that in a moment here. I have always been taught never
