After this commit it behaves like 'unfold f'.
That is, it will unfold f even if it fails to fold recursive

it cannot fold the recursive applications.

addresses this issue.

refactor(library/init): define prod as an inductive datatype
...
Motivation: prod is used internally in the definitional package.
If we define prod as a structure, then Lean will tag pr1 and pr2 as
projections. This creates problems when we add special support for
projections in the elaborator. The heuristics avoid some case-splits
that are currently performed, and without them some files break.
