in reply to GOTO considered (a necessary) evil?

In well-defined cases, such as jumping to the beginning or end of a loop, we have special keywords that mean this. It is not as bad as goto because you know what they mean in terms of structure, and we also have idioms that go with them.

"Go back to the beginning" is a well-defined point, not a random jump into the middle of the logic.

Check out the redo keyword. I've used it in cases like this.

[stevieb]: I've finally added the ability for berrybrew to fetch the list of perls available directly from Strawberry's releases.json file. Instead of pulling from there on every single call, I've added a berrybrew fetch, so it's only updated..
[stevieb]: ...on request. There's some supporting work I need to do, as well as update the docs, but it's in the v1.12 branch if anyone wants to play with it...
[stevieb]: ...issue 62 will track what else needs to be done.
