I don't think there should be two syntaxes here. Either allow
expressions on the left side of the ':' or always use '=>' and require a string
on
the LHS. The example already allows for using a string on the LHS in
{"foo" => 1}, so I think that the most useful choice. I don't think in
{PROPERTY_NAME => 1} , the LHS should be interpreted as the literal
value PROPERTY_NAME, but only the value of that constant.
