| Subject: | bare `Exists` not working under TkHijack |
If a program uses `Exists` (and possibly other symbols) instead of `Tk::Exists`, an error results:
Can't locate object method "Exists" via package "MyPackage" at MyPackage.pm line nnn.
One workaround is to replace `Exists` with `Tk::Exists`.
I'm not yet sure what causes this. Tcl/pTk.pm does have `@EXPORT (@perlTk, …);` where `my @perlTk = qw(… Exists …);`, and TkHijack.pm redefines `Tk::Exists` to `Tcl::pTk::Exists`. And most other bare symbols like `MainLoop` seem to work fine.
