Here, here!

Suggestion:

base library implements:
  epcall(errfunc, f, ...)

compatibility code:
  function pcall(f, ...) return epcall(nil, f, unpack(args)) end -- *
  function xpcall(f, errfunc) return epcall(errfunc, f) end

* unpack doesn't really work here, as Wim has noted. But I think that 
will not be an issue with 5.1, and it certainly wouldn't be an issue in 
C.
