Rough idea:
Tolk language [recommended]
Overview
...
Other languages
FunC [legacy]
Fift [legacy]
Tact [deprecated]
...
Blockchain fundamentals
TL-B
...
Plus, add another callout or expand the existing ones, saying that TL-B, FunC, and Fift will be eventually (1 month span) moved into blockchain fundamentals (or into their own, "Legacy" section), whereas Tact will be removed completely.
We cannot remove FunC and Fift until:
- Tolk is audited,
- Tolk has its own backend,
- system and important ecosystem contracts are written in Tolk,
- understanding of TON does not require dealing with FunC or Fift.
That is to say, FunC and Fift will at best be moved to blockchain fundamentals in a deprecated/legacy subsection and get reduced number of mentions. Neither of them will be removed from the documentation.
