Is there any chance, there will be codemods?
They could probably be made, but I still wouldn't rely on it.
Well working Codemods are difficult to make in many cases, and unless someone is paying for it, I don't think there will be many calls for one to translate between the syntaxes unless the proposal gains a lot of usage without settling on one.
The pipeline proposal has multiple syntaxes right now that the community is trying to pick from and discuss.
The chances that the F#-style syntax will be chosen AND will make it to the language proper unchanged is VERY low in my opinion.
And if the community goes in a different direction, it's unlikely that the F# style will be maintained for all that long because it's still such an early stage proposal.
