In the same way we currently have a local implementation of try based
upon TIP #89, we could make it compatible with TIP #329/Tcl 8.6 instead.
This could mean just importing the one from Tcllib (haven't checked its
license) and make it work on Tcl 8.4. I don't think there is a need to
wait until we have a bundled Tcl 8.6.

Of course this also requires adaptions of all uses of the try proc in
base, but that is only in a few limited places (around 30 times).
