These are different in other, more important ways as well. In
particular, `Loader.import` references a module name, (potentially)
fetches it, defines the relevant module, and returns the module
instance object to the callback, whereas `Loader.load` is basically
the (async) composition of XHR and `Loader.evalAsync`.

Yes, `.load()` is like `.evalAsync()`.

Using `export` at the top level of code passed to `Loader.load` is a
syntax error, the same way it would be a syntax error to use `export`
at the top level of any other script.
