What I want is to be able to interpolate links like: ⟦ (some-link) ⟧ on
the fly similarly Org links, in such way that whatever function
`some-link' returns it would be displayed on its place. Function may
return string or string as button or anything else. Then similarly to
org-toggle-link-display I wish to fontify such buttons in editable
buffer and be able to reverse it back. I guess for that to work text
properties shall be able to remember the button ⟦ (some-link) ⟧. But I
do not know much about it, I am learning.

I already use that system though not in editing mode. I have editing
more wher I can see ⟦ something ⟧ and I have presentation mode, where
source is interpolated on the fly and I can see interpolated values or
button links. 

System of interpolation spare me time.

I already use Hyperbole on links like ⟦ (rcd-db-tabulated-edit-entry "people" 1) ⟧
or ⟦ (hyperscope-action 587) ⟧ (the last one brings me to mail mode
with prepared email headers writing email).

It is not hard:
(defil rcd-template-eval "⟦ " " ⟧" ".*" "{M-: \\& RET}")

I can use command to interpolate the source and present it. It works
well. Editing in the same time with interpolated links is what I
miss. That I have in Org mode, but links miss dynamic capacity.

I would use Org buttons, but they do not have disappearing or dynamic
capacity. 

Text could have Hyperlinks, and be well referenced that way. In export
or interpolating mode, depending of the export type or major mode,
hyperlinks themselves may decide how to interpolate, if to disappear
from text, or if to convert themselves into Org links or into HTML
links, Markdown links, or Emacs links.
