In the spirit of the discussion about language complexity and
extensibility, consider the following brain-addled, pre-strawman proposal
for a new pick operator.

Thanks, some quite interesting ideas!
Some quick thoughts while reading:
* `o && typeof o === 'object'` should just test for `o != null`. Or at
least not ignore function objects.
* that array picker operator should be omitted. Nobody needs this,
picking from an array is very rare. Just use the standard `#` picker
operator, onto an array literal, with explicit property names if need be.
* Don't introduce a new syntax for computed properties, we have brackets
already. That `*` looks to much like generator functions.
However, instead of introducing a new operator I'd rather like to extend
destructuring and property shorthands to take more than single
identifier. The basic examples from your motivation could easily handled
by this, withoug looking much worse:
let pickedObj = {o.p1, o.p2}; // uses "p1" and "p2" for property names
{pickedObj.p3} = o; // takes "p3" as property name, assigns to LHS
`pickedObj.p3`
