You're of course right. I suppose my enthusiasm for the 5.1 module
system got me carried away.

It seems what I need is a general way to get the printable name of a
table (assuming that a module resides, one way or another, in a table).

A quick look at the debug library has not shown me an easy way to do
that so I'll have to try something homegrown. Or has someone an idea as
to how to do this?

(I know that whatever I'll end up doing it won't work with compiled
code; that's fine as this strict layer is more a debug measure than
anything else.)
