- Allowed parameter specification for setters. One can define now a setter with constraints like e.g. ::xotcl::setter o a:integer to define a setter named "a" for object "o" which has to be integer. - Extended regression test - Followed nameing conventions for several structures
- made error messages for failed conversions more consistent (note that tcl does not provide the parameter name in the error message, but user-defined converters do)
