Twittercan.isValueLike
Set to true to show than an object is usable like an atomic value (a number, string, boolean, or undefined value).
@@can.isValueLike = true
Shows that this object can be used as an atomic value; it may make sense to also implement valueOf() and @@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
setValueis returned bygetValue
