New submission from Serhiy Storchaka:

Command used to monitor Tcl variable access ("trace variable", "trace vdelete", "trace vinfo") are deprecated and will likely be removed in a future version of Tcl. Replacements ("trace add variable", "trace remove variable", "trace info variable") use slightly different syntax (operations are specified as a list of words "array", "read", "write" and "unset" instead of a string containing characters "a", "r", "w" and "u"). Therefore we need new set of methods.

Proposed preliminary patch adds trace_add, trace_remove and trace_info methods to the Variable class. It will be changed after applying issue22068 patch. Tests for old methods will be backported to older Python versions.
