can-symbol/docs/symbols-isValueLike.md

Well known symbols used to detail how to operate on different objects

@typedef {Boolean} can-symbol/symbols/isValueLike can.isValueLike
@parent can-symbol/symbols/type
@description Set to `true` to show than an object is usable like an atomic value (a number, string, boolean, or undefined value).

@signature `@@can.isValueLike = true`

Shows that this object can be used as an atomic value; it may make sense to also implement `valueOf()` and [can-symbol/symbols/getValue `@@@can.getValue()`]

In the case of a MapLike, an object is ValueLike if and only if:

* it always returns the same value from `getValue`; and
* the same value that is set from `setValue` is returned by `getValue`
