* There are two [[Construct]] operations in the specification:

*
* The chain of bound functions is resolved in Section 15.3.4.5.2,
* with arguments "piling up" until the [[Construct]] internal
* method is called on the final, actual Function object. Note
* that the "prototype" property is looked up *only* from the
* final object, *before* calling the constructor.
*
* Since Duktape 2.2 bound functions are represented with the
* duk_hboundfunc internal type, and bound function chains are
* collapsed when a bound function is created. As a result, the
* direct target of a duk_hboundfunc is always non-bound and the
* this/argument lists have been resolved.
*
* When constructing new Array instances, an unnecessary object is
* created and discarded now: the standard [[Construct]] creates an
* object, and calls the Array constructor. The Array constructor
* returns an Array instance, which is used as the result value for
* the "new" operation; the object created before the Array constructor
* call is discarded.
*
* This would be easy to fix, e.g. by knowing that the Array constructor
* will always create a replacement object and skip creating the fallback
* object in that case.
*
* Note: functions called via "new" need to know they are called as a
* constructor. For instance, built-in constructors behave differently
* depending on how they are called.
