bummer.  the pickaxe sort of implies it is :

...
        class methods
        [ ]
              Hash[ [ key => value ]* ] -> aHash
              Creates a new hash populated with the given objects. Equivalent to the
              literal { key, value, ... }. Keys and values occur in pairs, so there
              must be an even number of arguments.

              Hash["a", 100, "b", 200] � {"a"=>100, "b"=>200}
              Hash["a" => 100, "b" => 200] � {"a"=>100, "b"=>200}
              { "a" => 100, "b" => 200 } � {"a"=>100, "b"=>200}
...

i'm referring to the last bit.
