I need to know if the current procedural context is inside a method (isntproc, proc, whatever) or not. What is the best way to do this? I used [self] to check by catching the error, but that doesn't work particularly well if another package happens to define the command [self]. Besides, I've never been fond of having to resort to error- catching to find out information (a bit like how people used to test for the existence of an array element with [catch]).

can you explain in more detail, what the problem is? Note, that one can calls tcl procs from within xotcl methods, one can have evals, uplevels, etc.

use ::xotcl::self
"self" can be used to check whether the xotcl callstack is non-empty.
without promising to much, a sucommand"ismethod" for "self" retuning 0 or 1 depending whether the current stackframe is an xotcl method should be doable with little effort.

I have a debug library that automatically displays information about the proc or method in which it was called, to get the context for the information. I want to check that if I'm running in an XOTcl method, I also want to display the class for it.

Good idea.

Yes, but only by wrapping it in a [catch].

Worth considering. It's not perhaps high-priority, but might make it neater.
