Detail #267: Extracting Certain Verbal Markers in Coordinated Structures

Think of structures along the lines of coordinating things like

go-past or go-fut?

in the context of, say, clarifying that you are not sure you heard right.
What if certain TAM markers were somehow extractable -

go-3sg-past or-3sg-fut?

In essence, "or" would be partially verbal there. We could also have things like

talk-3sg-pres and-3sg-pres and-3sg-pres
he talks and talks and talks

Maybe one could form larger complexes of extracted TAM markers:

sing-1sg-past and-1sg-present-and-(1sg)-future
I sang, I sing, and I will sing

Maybe the person can be omitted, maybe this only is permissible with the same person carrying over or maybe even a change in person could be introduced as well:

sing1-sg-present and-2sg-present
I sing and so do you

Maybe we don't even need to extract the TAM:

sing-1sg-present and-2sg
I sing and so do you
