Shouldn't "call" be differentiated into "call" and "rawcall" similar
to getglobal et al?
I think there should be a way (the default) to have "call" respect tagmethods.
Upto now "call" behaves like all those "rawdosomething" functions.
Of course I can always do:
local rawf = gettagmethod(tag(f), "function")
call (rawf, args)
.. but I think the first line should not be necessary, right?
