inspired by javascript support for object literal shorthand notation `{ a }`, which will be expanded into `{ a: a }`..
to avoid ambiguity, this shorthand is only supported when hash is defined with `{ }` notation.. in other situation where the brackets is optional, e.g. function call, we still need to write it in full (`m(a : a)` instead of `m(a)`, or `m(a, b, c: c)` instead of `m(a, b, c)`..
