I do too. While terseness clearly contributes to understandability,
regularity and simplicity do too. When these conflict, we should be very
careful about sacrificing regularity.
Currently is JS, x['foo'] and x.foo are precisely identical in all contexts.
This regularity helps understandability. The terseness difference above is
not an adequate reason to sacrifice it.
