alt Hacker NewsThe lack of unit tests is something I'm guilty of too and you're very right about it. The community is dimly aware of the fact that systems are more on the "academic prototype" side of things and less on the "enterprise software" but there's so little interest from industry that nobody is going to spend significant effort to change that. Kind of a catch 22 maybe.
How about ISO? Why was this a requirement, out of curiosity?
Quantum Prolog is pure ISO and was the primary target for porting here. The idea is really just putting effort behind libs that can be shared by other non-legacy Prologs and thus get more people involved.
