But as to who(m) -
I too never/rarely try to recollect the mechanical parsing rulez of eons back.
"How does it scan" - isn't precise, but properly pulses 'all experience'.
I'm sure I never 'memorized' all those blackboard parsing exercises; that's just manna for compulsive taxonomists.
I must just remember the resultant engrams. I think !?
Then too, if one recalls Subject/Object .. that correlates with the transitive or intransitive case of [the meaning of is.] But not so simply, with only one to Be extant. Espa\ufffdol is saner, with ser and estar to obviate most vagaries of Being.. stuff
Here's a test of your eclectic amassing of English weirdage of the Ages -
It is I, Digby O'Dell the {friendly} undertaker [1]
-VS-
It's me.
I think there's no punctilious way to parse these, without separate verb-forms.
I can ~take It's me, which is by now std. usage, I wot - but prefer, It is I.
If you reverse the order, as one should be able to to do, in intransitive case:
It is me <-> Me is it.
-VS-
It is I <-> I is it, though {sigh} you'd really say, I am it/I am that (-person) {ugh}
Easier, when queried about a definite, Are you he? -- clearly you reply, I am he (not him) etc.
Too many words! about a couple simple idioms. You're really not 'acting upon' the putative object here, ergo I aver that Engl. would be much saner with ser/estar.
We. must. revise back to... beyond Beowulf.
er,
Maybe 'scan' Is the better working version. :-\ufffd
