Two minor changes to the way python snippet expansion happens
- Use a single dictionary for the context, both global & local, since for some
reason it chokes wanting a global "d" rather than a local in the metadata.
- First compile the string into a code object before running eval, so we can
include the variable name in an evaluation error.
