i've just read the pep (it seems to be doing the rounds in blogs) and haven't followed the discussion, so this might have been covered (although searching google for tertiary and lazy on the group turned up nothing). if using a funcion like cond(a, b, c) doesn't work because of eager evaluation of parameters, you might consider adding lazy evaluation to python. i would guess the general consensus on this is something like "lazy evaluation may be powerful in some cases, but we can get the same functionality in other ways and we don't want to scare the bejeezus out of newbies". to which i'd reluctantly agree. but it can be so neat, and maybe someone smarter than me can find a super-elegant syntax, "or something"... cheers, andrew -- http://www.acooke.org/andrew
