We should release #4428 ASAP.

I think we need to mention this in the changelog, too:

commit 1143ac0268f3d96354ef156e78435716368053f6
Author: Chris Connelly <[email protected]>

    Allow `@` values as indices in `for` expressions
    
    This loosens the compilation of `for` expressions to allow the index
    variable to be an `@` value, e.g.
    
        do @visit for @node, @index in nodes
    
    Within `@visit`, the index of the current node (`@node`) would be
    available as `@index`.
    
    Fixes #4411.
