can't use the debugger with elm-reactor

I'm trying to use the Debugger with elm-reactor but I get this error:

`Debug` does not expose `watch`.

I'm importing the Debug package:

import Debug

as per the mouse example

As of 0.17.0 release, Debug package no longer exposes watch function.

Debug.watch only makes sense in the context of Time-Travel Debugging, which is not available in 0.17.0 release.

The example you are referring to is written using Elm 0.16.0, any examples using Signal package are not relevant anymore.

See more details on the latest release in the official blog post from Evan: A Farewell to FRP

watch was removed from Debug prior to the release of 0.17.

Here is a discussion about the decision which oscillates between moving watch and watchSummary to a new Reactor module (since they were only useful within elm-reactor), or replacing them altogether with log and logSummary. Neither of these resolutions have happened as of 0.17, so we are left without them for now.
