- changed Stack example in tutorial from constructor to :variable - allow just valid specs for :attribute and :variable methods - improved error message for invalid parameter specs (with leading colons) - extended regression test
- fixed book-keeping for TclNamespace refcounting such that now alias.test, destroy.test and test.xotcl run now clean, 2 test are still open with tcl 8.5.10 (contains.test and xotcomm.test)
