Ok, I should update the Specification and state more clearly how these

With the current patch, call [tcl::seterrorhandler] withoud arguments. 
This gives you what is registered currently.

Again with the current patch, call [tcl::seterrorhandler {}] to

to register the custom handler... (but this is for sure the easiest 
thing to change). If someone has a better idea, please let me know.
