Functional syntax (Was: RE: [mercury-users] Hi, and determini sm)

[Richard A. O'Keefe]

Thomas Conway <conway at cs.mu.OZ.AU> provided an excellent example of
space-saving, which however did not use bitfields.  The space saving
came from eliminating certain fields entirely because their values
could be determined by other means.
	
Has anyone an example where packing below the byte level would save
useful amounts of memory, in Mercury?

I used to program in Burroughs Algol, BLISS-10, and Progol, all of which
had bitfields more-or-less along the lines of
	integer_variable.[offset:width]
I'm so glad I don't have to do that any more.
