It would have probably been better if xpcall had started as:

logical :
xpcall(err_handler, f, arg1, arg2, ...)
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
