RE: The poor state of documentation of pcase like things.

[Phillip Lord]

It matches anything (like a variable) but does not actually bind a variable.

It's also being used in other parts of Emacs -- I've used it for generic EIEIO 
methods

(defmethod blah (a b _))


to mean "I have to have a parameter, but am not going to use it", although it's 
just a symbol
like any other and binds a variable. IIRC it shuts byte compiler warnings up 
about unused variables.

Could someone report on what the current meaning of _ is?
How is it actually used in pcase?
