Description

For earlier discussion, see https://github.com/rust-lang/rust/issues/14726
This issue was labelled with: A-syntaxext in the Rust repository
I wanted to create an issue first asking about this before submitting a pull request.
Can I go ahead an implement hashmap!(), hashset!(), treemap!(), and treeset!() macros for constructing those collections with the given arguments? The syntax would be:
let h = hashmap!("foo" => "bar");
let s = hashset!("foo");
I already have these macros implemented in my own projects, so I'd just have to add them to macros.rs.
If I can add these, is there a process for testing macros? Or would I just replace all occurrences of hash{map,set} and tree{map,set} creation in the tests by the macros?

Research direction
Start with macros.rs and the earlier discussion in Rust issue #14726, then read the linked comment thread for the proposed collection-macro design and testing process. Done means the requested hashmap!, hashset!, treemap!, and treeset! macros have an agreed implementation and appropriate macro tests.
