I believe the consensus was that nice JSON input syntax could be handled
with a macro.
Also, once the "[ a=>b, ...]" syntax deprecation goes away, I believe this:
[ :col => "l1", :col => "l2", ... ]
will simply give you an array of Pair objects, which could be translated to
unitary Dicts by JSON.
(FWIW, it is not necessary to specify the argument types to Dict)
