which is a lazy functional description language for pages.

Thanks, I downloaded the system and looked at a few pages of the manual ... now I need to understand why it is a lazy functional description language, but that I have to postpone :-)

evaluation of macro arguments proceed "as needed", for example a macro can produce an infinite list of ".", but the consumer function can decide only to take a finite amount of them (for example to create the .... in a table of contents). In a funcitonal language with strict evaluaiton the infinite list would produce a loop. Similar behaviour in non-lazy languages is obtained via "promises", generators, etc..
