I guess we would like to have something like, for example fo scf.for:

```
region-arg($body) `=` $lowerBound `to` $upperBound` step $step `iter_args` `(` region-arg($body) `=` $init `)`
region-body($body)
```

Underneath I imagine this would use two phase parser 1. parse region arguments 2. parse body and forward its parsed arguments to it.
