Improve feedback when exceptions occur while compiling dispatch table #14

Closed hlship closed 10 years ago

hlship commented 10 years ago

Currently, the exception doesn't provide any sort of useful context:

We need to provide more information, either via io.aviso/tracker, or by additional try blocks to capture more details about what function of what namespace contains the error.
