Bad call. I assert that it is useful for pure lua too. In fact it's
almost 100% necessary for the class system I'm putting together. The
naming of it __getmethod is certainly better than my original __methcall
but I think I prefer __method to be consistent with __index

[snip rest]

the lua_getmethod() thing you suggested I think would be far better
served with something more like.

Given object at index obj

lua_pushstring(L, "foomethod");
lua_pushnumber(L, 12);
lua_pushstring(L, "otherarg");

lua_mcall(L, obj, 2, 1); /* call a method in obj given two arguments and
the method before them. return one value */

Then provide the obvious gamut of lua_pcall etc with the 'm' variant for
added happiness :-)
