I frequently see this idiom in the code in plugins and pre/post callbacks:
My understanding is that keys in the positional parameter list of the
keys always appears in a formal parameter list with the parameter
"options", which I believe are the keyword arguments of the command
(i.e. *args, **kwds)
Thus keys[-1] would be the last positional parameter. What is special
about it such that one can always reference the last positional
parameter? (or have I misunderstood, if so please elucidate).
If keys is the positional parameter list (e.g. *args) why is is called
"keys"? That seems really confusing because keys usually has an entirely
different meaning (i.e. keys of a dict). Why isn't it named "args"?
