Deep recursion while scanning topic inheritance! - not helpful :)

[dcsan]

I see this error often debugging end user scripts, but it would be great if it said which topic was causing that issue. debugging on big projects is really difficult.

great, installed 1.17 to have a look at this, however the error now:

mtl-1 (err): Deep recursion while scanning topic inheritance (gave up in topic shared)!

we have a topic called shared which is inherited by a lot of things, but an error with just that topic info is hard to pin down. it would be very helpful to see the whole inheritance tree or get some more info.

For diagnosing things like that you could turn on debug mode and scan through the output. It's probably caught in a circular loop. It should log debug stuff for each topic it's on, along with other helpful info (how deep into the recursion it's at, etc.)

ok i'll try debug. that works at parse time too? ok
I also used deparse to see if i could spot where it was... but with a lot of topics that's hard to scan too.
