I oriented this on the syntax of array slices. Which work that way. Not inconsistent at all. It's also consistent with foreach(_; x..y).
It would look consistent, but it would behave very differently. x..y for foreach and slices is exclusive of the y, while case x..y is inclusive.


The current way has that inconsistency:

variable .. variable   // exclusive end
caseLabel .. caseLabel    // inclusive end

And yes, I know that's not how it's actually parsed, but that's how people visually parse it.

I don't think so at all. There's a lot of punctuation that has different roles depending on the context. For example, ":" means key/value separator or ternary operator participant; "*" means multiplication or pointer dereference; "&" means taking address or binary "and"... plenty of examples. So you can't center on ".." and claim that it visually means the same thing even though the surrounding is different. You really have no argument here.

Ah the hell with it, I don't care any more: The *real* issue here is that the current switch, being based on C's, is horribly antiquated and what we really need is a comprehensive redesign incorporating some sort of generalized pattern matching. Like "case > 1, <= 10:" or something like Nemerle, or whatever. I don't care, as long as it doesn't continue to get trivialized as something that can be solved by tossing in a recycled ".." here, a recycled "final" there, etc.

On the full side of the glass, with the latest dmd release, the language has acquired some useful feature improvements and the implementation has fixed many bugs. Why the crankiness?
