[Ecls-list] Loop and order of until clause

[David_Creelman at pa.com.au]

Hi,
I tried to get GameLib to compile and ran into several uses of loop where
the until part of the loop was at the beginning, not the end.
Is this valid Common Lisp?
If it is, how easy is it to change in ECL?
I haven't used loop myself, but it might be good to get it to work to
standard if this is the standard.
Regards
David
