Why are you not adding |code| to the constructor signature?

[Habib Virji, 2014/11/24 15:12:22]

Since the constructor is used by inspector, there was a review comment
mentioning not to change constructor signature in a inspector-1.1.json,  so did
not wanted to disturb the constructor behavior. Have added back again, to make
it consistent. Plesae suggest if it's okay.
