Introducing Multi-valued Variables

Personally, I’d really prefer single round brackets to double angle brackets for this usage. We spend so much time telling people not to use constructions like my.function<<multivaluedvarname>>; I imagine that confusion will only increase if new users are encountering that sort of syntax.

I’ve pushed an update to add support for single round brackets, which also allows the “varlist” operator to be removed. Once again, it seems like a big win.

But I’m curious as to whether we would have an obvious parallel for double parentheses outside a filter.

Very good question. Perhaps ((my variable)) should take a cue from {{{ filter }}} and display all of the results with wikification. On the other hand, I never liked the behaviour of {{{ filter }}} and so we probably shouldn’t perpetuate it.

Maybe instead of just concatenating the results, ((variable) should wikify them with a double line break in between each item. That would generally mean that paragraphs would be generated, which would make things much more readable. It would still largely be a tool for debugging, I suspect.
