A nice example of this is Joe Armstrong's "bang-bang", i.e. the
!! notation for a synchronous process interaction.

Not only did he implement the language feature -- he wrote
a GUI framework with lots of example code using it.

Not that it was adopted anyway, but a nice example of
someone actually walking the talk it was.  (:
