Improve see error message

[adsteel]

Currently the error message can be a bit misleading.

"Unable to see your_widget and my-class".

If the widget is defined in part by the class, the error message would be better as:

"Unable to see your_widget with my-class".

Or to even pull the argument names if possible, to give:

"Unable to see your_widget with klass = my-class"

We still want the error message to make sense for custom see methods as well, though, where currently the "and" makes sense.

Weird, just leaving a comment unassigned me. If only I knew where to file the bug... 😉
