Happy New Year!
I know there are filters, but I am looking for an easier way to
[..]
Why not use filters with filterguards? I would've thought that would be the exact mechanism required.
Yes, it would be possible to do it that way, but it is very complicated: - Register a filter that is by default applied to _all_ instprocs - restrict the appliance of this filter via a filterguard
Sounds like "shooting from behind through the brest into the eye". Why not simply add/remove execution of code to particular methods, like with [trace]? There is already a [trace] method for XOTcl objects, but just for variables (at least from the documentation)... Especially I look for a way to execute a proc before *every* statement inside an instproc. [trace] can do this via the "enterstep" and "leavestep" operators to [trace add execution]. Is this possible with filters and filterguards?
