I suggest that if it is used, the "use strict" is inside the AMD
factory function. There are issues with combining code that does a
"use strict" at the top with code that is not "use strict" friendly. I
have hit this with requirejs, so just something to be aware of. I have
gone to a model of not using "use strict" but using JSLint to lint the
code, I feel like it gives a decent tradeoff on getting the form in a
more strict form. Although I'm curious where the gaps are with that
approach vs. explicitly setting "use strict". I am sure there are
some, the default value of "this" in unbound function calls probably
being one (which we should not be relying on anyway).
