[tcltk-perl] why autoloading in Tcl/Tk do not work from Tcl::Tk?

[Vadim K. <va...@ar...>]

Does anyone has an idea why autoloading does not fully functioning when
Tcl/Tk is used from Perl?

As an example,
     $interp->call('tk_setPalette', $color);
does not work: it fails to find tk_setPalette procedure

But following works:
     $interp->Eval('tk_setPalette '.$color);

and once that code is executed previous piece of code also works properly.

Code for that function lives in a file lib/tk8.4/palette.tcl

Same thing for tk_optionMenu

Best regards,
Vadim.
