This idea is very interesting.  I have committed an experimental patch
that extends \directlua syntax so that besides

    \directlua <number> <general text>

it also allows a keyword prefix:

    \directlua name <general text> <number> <general text>

This allows you to do stuff like this:

    \directlua name {\jobname-\the\inputlineno} 0 {error('test')}

Because it is experimental, it only works for \directlua, not
yet for \latelua.

Best wishes,
