Yes, it seems to be a necessary requirement.

IMHO @(...) has two advantages over '[]' approach:

1. It keeps all that 'additional scope'-stuff in a separate line, making
the code probably more clear visualy, and not making the crowd of
elements in the '...):' line even more dense (especially if we did use
annotations, e.g.: '...) -> "my annotation":').

2. It is more consistent with the existing syntax (not introducing
'='-based syntax within []; [] are already used for two different
things: list literals and item lookup -- both somehow leading your
thoughts to sequence/container-related stuff).

Cheers.
