I know about this. I was trapped by it as well...
Shortly, AS has some issues in this respect, which has nothing
to do with ttrace package itself but with the argument passing
out of the C-code within AS (historical reasons, I believe).
I wanted to go and look into this but still haven't done that.
Maybe this is the right time to do so...
BTW, all our Tcl callbacks are like this:
proc some_callback {args} {...}
since I never figured out the *complex* argument passing rules
imposed by the AS in this special case.
Cheers,
Zoran
