I feel very uncomfortable about speaking up in opposition to a much more experienced person, but I'd like to register a vote against this idea. The whole reason that we're building Perl6 in the first place is because there is a lot of nasty cruft in Perl5. We are working towards creating something clean and elegant; let's not start out by putting things in just because they are "trivial to code" when we don't have a use for them. In general, I would like to see the policy be "unless there is a clear and demonstrated need, we don't do it." Let's just make the engine easy enough to change that, as we discover things we didn't know we needed, we can go back and add them in later. Dave StorrsThread Previous | Thread Next
