Graham has done much of the work (investigative, as well as code) on this already so we should be able to get to that point "soon". Graham wrote into this thread, but I don't think it seems like we're expecting an RFC, so I'd rather this not stagnate. It seems like the thrust of Graham's post was "yes, a `load STRING` would be useful, but we want to distinguish between kinds of failure." I agree, and I think we want that from `require`, too, and I also think that "an exception system would solve this" is the kind of thing that can stymie a lot of stuff because it wants to plumb stuff into all parts of Perl. Instead, I propose that the next step here is to provide a load-at-runtime built-in that expects the name of a module and dies on error. At some future time, if we overhaul exceptions, we can fix both it and "require" then. In the meantime, I don't think it's economical to make load-at-runtime wait on an exception overhaul. Thoughts? Shall I write the RFC? -- rjbsThread Previous | Thread Next
