FYI: I just found that the 'Ttrace' package (provided with TCL, https://www.tcl.tk/man/tcl/ThreadCmd/ttrace.html) interfers with the
loading of tablelist:
$ wish8.6
% package require Thread
2.8.7
% package require Ttrace
2.8.7
% package require tablelist
invalid command name "extendConfigSpecs"
% info patchlevel
8.6.12
Whereas loading tablelist first works fine:
% wish8.6
% package require tablelist
6.16
% package require Thread
2.8.7
% package require Ttrace
2.8.7
I don't think this is a tablelist issue, since loading Ttrace has other strange sideeffects, too:
$ wish8.6
% package require Ttrace
2.8.7
% set tcl_platform
can't read "tcl_platform": variable is array
% parray tcl_platform
"tcl_platform" isn't an array
Whereas:
$ wish8.6
% set tcl_platform
can't read "tcl_platform": variable is array
% parray tcl_platform
tcl_platform(byteOrder) = littleEndian
tcl_platform(engine) = Tcl
tcl_platform(machine) = x86_64
tcl_platform(os) = Linux
tcl_platform(osVersion) = 5.3.18-59.27-default
tcl_platform(pathSeparator) = :
tcl_platform(platform) = unix
tcl_platform(pointerSize) = 8
tcl_platform(threaded) = 1
tcl_platform(user) = ralf
tcl_platform(wordSize) = 8

The "package require tablelist" works fine if invoked before loading the Ttrace package, but some Tablelist operations (e.g., moving the
columns), will fail later on.

The bug is in Ttrace. This package renames the unknown proc to ::tcl::unknown and provides its own unknown command implementation in
the file .../lib/thread2.8.7/ttrace.tcl. Line #328 of this file (part
of the new unknown proc body) reads:
set c [catch {::eval ::tcl::unknown $args} r]
This line must be replaced with
set c [catch {uplevel ::tcl::unknown $args} r]
After patching the file in this way, everything works as expected.
I will submit a ticket regarding this bug.

Great, thanks for the analysis and the ticket!
