Currently, Xap.require() won't throw an error if there's an underlying problem loading a class. Would anyone object to my altering Xap such that it will in that case (currently, iff dojo.require() throws an exception)?
It might induce errors showing up, but I, for one, welcome knowing about them. (In the mean-time, I'm making the method return a boolean based on success; that will affect no-one else.)
