In the release notes for Alpha 6, there's a Functional Interfaces section where it says "Note: this will be available in a future alpha." but the Java Supplier Interop subsection did make it into Alpha 6. Curious about why the FI stuff got documented but didn't make the alpha, and whether there's a timeline in mind for it to make a future alpha?

it's part of the story, so felt weird to leave it out, but the work needs to be rebased over the method values stuff. hopefully will be in the next alpha

Cool. But no timeline for that yet?

Haha... it was worth a try... 🙂

"soon" I hope :)

In the description for https://clojure.atlassian.net/browse/CLJ-2805, it says:
> Type hints can be any type hint specification currently accepted -- fully-qualified class symbols, imported short class symbols, or “special” type hints representing primitives (like ^long, double, etc.) or arrays (like ^longs, ^objects, etc.), or strings.
Does this mean that e.g. ^{:param-tags [^long]} MyClass/myMethod should work? i.e. with the ^ in ^long?

That looks like it should be a read error to me, but the description is a little ambiguous.

Which makes sense, I think.
