Description
yank-last-arg was enabled for Emacs binding as part of #343.
It would be very useful to have it enabled for Vi binding as well.
I'm using Xonsh and as a workaround for the time being I am using this binding:
@events.on_ptk_create
def custom_keybindings(bindings, **kw):
@bindings.add('escape', '.')
def yank_last(event):
event.current_buffer.yank_last_arg()

Research direction
Start by tracing the Vi binding setup and the existing yank_last_arg implementation referenced by the workaround. Verify how the escape-plus-period binding is registered and test that the Vi binding invokes current_buffer.yank_last_arg(); done means the key sequence works without a custom Xonsh binding.
