To supply new functions forSystem functions, extendTraceurLoader and override the functionsnormalize,locate,fetch,translate orinstantiate. The first three are supported and we'll fix any bugs against them. Thetranslate andinstantiate are called but probably don't do what the standard expects.

For example, you might do something like

import{webLoader}from'./webLoader';classMyLoaderextendsTraceurLoader{constructor(){super(webLoader,window.location.href);}normalize(name){// bah I am normal!returnname;}}System=newMyLoader();
