My experience with AMD and require.js is that it is very useful for the
error to include not only the module that couldn't be loaded but also the
module that requested it. These two fields should be on the Error object,
and so a new ImportError with the field `missingModule` and `requestedBy`
(or something similar) sounds like a good solution to me.
