I believe that for Yhc, as long as the extensions are after the last
import, they won't be read. The parser is sufficiently lazy that it
can get the import declarations out of a module without parsing the
whole thing.

This gives both a performance boost, and happily ignores extensions.
Although I suspect a custom parser for import files would be best, to
get maximum flexibility.

Thanks
