Tcl Library Source Code

Hi Andreas!

Pls. consider the improvements on branch pt-fixes2-ssoberni [9877877dcd] for inclusion into the mainline (maybe also the 1.19 rc?).

Background: Working on the FFP patch, I realized that the debug mode was broken for the NX engine, because of the subtle differences between TclOO and NX when it comes to namespace contexts. I fixed this, one can now "debug on pt/rdengine" and "debug off pt/rdengine" as available for the other backends. Along the way, I also micro-improved the generated NX code so that the typical instruction methods (in non-debug mode) run ~25% faster on standard parsing loads (by managing variable imports à la TclOO in NX more selectively). 

The pt test suite runs just fine. There are no API changes or backward compat issues, so a bump of version numbers should not be necessary.

Thank you for your help.

Merged to release, commit [720355a2d8]

Merged to trunk, commit [3a942ffbf3]

Looks ok. Currently running tests.

Agreed. I bumped the patch level. I also refactored some [expr] calls in [f94401b3e2], I hope this is fine with you?

So the commit and it looked easy enough.

The change to the debugging can be seen as bug fix, with patchlevel version increment. You actually describe it as such (... broken ... I fixed ...)
