If we try to write like this:
//EXAMPLE CODE
/obj/paper_creator/var/text_on_papers = "Hewwo"
/obj/structure_creator/Click()
    new/obj/paper{text = text_on_papers;}()
    var/t = "Another hewwo"
    new/obj/paper{text = t;}()

We will get cross-reference loop or undefined var, I think it’s worth to make some way to get vars of proc or of object that creating it with new{}()
Maybe something like in-{} vars like myBase or myProc or anything else that will contain ref of creator or vars of proc.

So it can looks like this:
//EXAMPLE CODE
/obj/paper_creator/var/text_on_papers = "Hewwo"
/obj/structure_creator/Click()
    new/obj/paper{text = myBase.text_on_papers;}()
    var/t = "Another hewwo"
    new/obj/paper{text = myProc.t;}()


I haven't problem with workarounds of this like change vars after creation of instance like:
/obj/paper_creator/var/text_on_papers = "Hewwo"
/obj/structure_creator/Click()
    var/obj/paper/P = new/obj/paper()
    P.text = text_on_papers

But it will be cooler without this workaround

I think what you're looking for already exists. BYOND uses atom.New() as a constructor function:

obj/paper
    text_on_paper = "Hewwo"

obj/paper/New(t)
    src.text_on_paper = t

mob/Login()
    var /obj/paper/p = new ("uwu uguu~~")
    src << p.text_on_paper // uwu uguu~

Dude, sorry, but i already told that i haven't problem with that... and prefabs already exists, i isn't request feature like 'new{var = value}()', i request ability to replace value in 'new{var = value}()' on some var not on in-code constant...

And please don't use "src." :c

Your "workaround" is what LordAndrew suggested and probably the best use.
