Not quite.  The reason they don't work is because, when we use them,
we often give them a *very specific* meaning.  Occasionally it's "do
whatever you want by default".  More usually, it's "do something
specific that doesn't have a good name, but that we consider a
reasonable default behavior".

In the second case, you can't change the meaning of the keyword to
that if it already means something like, say, 'initial'.
