Overview
Comment: | fixes [777ae99cfb]: previous var-lookup in class body (in ::itcl::parser) could obtain inherited common vars, be sure it does not exists after new uninitialized common creation; more test cases covering corner cases; remove unneeded calls of Itcl_BuildVirtualTables, since resolveVars is build on demand (moved to ItclResolveVarEntry). |
