Actually, the algorithm in the current (Rev16) draft does not treat these as equivalent. ArrayBuffer( ) will thrown according to the algorithm.
However, there is an issue in Rev16 in that the prose description in 15.13.5.still said that ArrayBuffer ( ) and new ArrayBuffer( ) are equivalent. That's simply an editorial bug that has already been corrected in my working draft for Rev17.
A good example, of why I try to minimize redundant prose descriptions and why reader should always use the algorithms as the primary definition.
