Comment (by MikolajKonarski):

 I'd like to point out that the combination of `-fexpose-all-unfoldings`
 plus `-fspecialise-aggressively` has the effect of `INLINEABLE` on all
 overloaded functions in the program. This is much less fine grained than
 the proposed `SPECIALISE_RECURSIVE`, but it works for me at the cost of
 much higher compilation times (e.g., travis now refuses to compile my
 program with `-O2 due to memory constraints). I wish somebody told me
 about that trick before I added my 600 `INLINABLE` and started writing
 corresponding 600 `SCC` pragmas by hand, so I'm sharing here. :)
