For function signature you have quite common representation `(%arg1 : type1, %arg2 : type2, %arg3 : type3, ...) -> (return-types)`
which you can uniformly abbrevieate in ODS as `function-signature` for instance.

But with loops you have various forms:
- `scf.while (%arg1 = %init1) : (f32) -> i64`
- `scf.for %i = 0 to 128 step %c1`
-  `scf.parallel (%iv) = (%lb) to (%ub) step (%step) init (%init, %init)`
