During testing of tcl8.5 with the tcl8.6 test cases, it became apparent that there are numerous
serious (core) bugs in tcl8.5 that were only patched in tcl8.6. However, tcl8.6 is now the problematic
release with NRE and TCLOO. In a first attempt to patch tcl8.5, a large amount of code had to be
imported from tcl8.6, which then raises the question of whether it even makes sense to patch tcl8.5
towards tcl8.6 if the end result is tcl8.6 anyway. The strategy of starting with tcl8.6 and removing
everything that is unwanted seems to make more sense to me because it starts with a bug-free launch
that is then successively retested at every step.
