No need to read the source lines from file.
caller(EXPR) gives you the subs name already as 4th return value.
See caller for details.
never mind, I just realized that you still want to parse the code where the call happens, because the error happens in the args-list there debug("x=$x y=$y");
That's pretty much as stable as a source filter.
Why not relying on Smart::Comments then?
