Right. Decompilation with ASR should be relatively easy and more faithful than average decompilation (though, as mentioned by another commenter, the very-long-term value of decompilation in general is debatable in the face of rising AI like CoPilot).
By being a superset of Fortran and subset of Python. It turns out the features map on each other almost 1:1, and the differences can be taken care of by the respective frontends, so the abstracted ASR maps perfectly.
