\item Calling Tcl methods through \module{_tkinter} now does not

always return strings anymore. Instead, if Tcl returns other objects,

those objects are converted to their Python equivalent, if one exists,

or wrapped with a \class{_tkinter.Tcl_Obj} object if no Python

equivalent exists. This behaviour can be controlled through the

\method{wantobjects} method of \class{tkapp} objects.

When using _tkinter through Tkinter.py (i.e. for most _tkinter

applications), this feature is always activated. It should not cause

compatibility problems, since Tkinter would always convert string

results to Python types were possible.

If any incompatibilities are found, the old behaviour can be restored

by invoking

\begin{verbatim}

\end{verbatim}

before creating the first \class{tkapp} object.

Please report any such breakage as a bug.
