First, thank you Miguel and klappnase for your patches. But they should be
provided in different way, as described in Python Developer’s Guide [1].
> I totally disagree of this change on your patch:
This is not my patch. This is regenerated klappnase's. I expected this will
allow to use the Rietveld Code Review Tool for reviewing, but unfortunately
Rietveld don't accept these patches [2]. Below I added comments to the patch.
I agree, that all these complications are not needed. Just use getboolean(). It
always returns bool in recent Python.
And don't bother about _configure(). Just duplicate the code. It can be
refactored later, in separate issue.
Since this is a new feature, it can added only in developing version (future
3.7). Forgot about 2.7 and 3.5. If make the patch fast, there is a chance to
get it in 3.6 (if release manager accept this). But tests are needed.

There was an attempt to deprecate wantobjects=False (issue3015), but it is
useful for testing and I think third-party program still can use it. If you
encounter an error because some standard method return Tcl_Object, please file
a bug. This is considered as a bug, and several similar bugs was fixed in last
years.
Here are comments to the last klappnase's patch. Please add a serial number to
your next patch for easier referring patches.

Shouldn't it be just an alias to tk_busy_hold?

Since the only supported option is cursor, just declare it.

"-cursor cursorName" is not Python syntax for passing arguments.

Just return the result of self.tk.getboolean().
