This JOSS paper would benefit from a Discussion / Future Work in which the authors, with their expertise, could point to future directions in this area.
I have added a new section to the manuscript, detailing future directions for the catalyst hybrid compilation stack:
# Discussion and future work
The Catalyst hybrid compilation stack as presented here provides an end-to-end infrastructure
to explore next-generation dynamic hybrid quantum-classical algorithms, by allowing for
workflows that support compressed representation of large, highly structured quantum
algorithms, as well as mid-circuit measurements with arbitrary classical processing and
feedforward.
The Catalyst software stack will continue to be developed alongside research, algorith, and
hardware needs, with potential future work including support for quantum hardware control
systems, building out a library of MLIR quantum compilation passes for optimizing quantum
circuits (without unrolling classical control structure), and explorations of dynamic quantum
error mitigation and proof-of-concept error correction experiments.
Quantum software is driving many new results and ideas in quantum computing research, and the
PennyLane framework has already been used in a number of scientific publications
[@delgado2021variational; @wierichs2021general] and educational materials [@demos]. By enabling
researchers to scale up their ideas and algorithms, and execute on both near-term and future
quantum hardware, the software presented here will help drive future research in quantum
computing.

Comment:
On balance, the paper has motivated the need, described three critical pillars of the JIT compiler infrastructure, and made significant open-source contributions.
My takeaway from reviewing this paper is that fault-tolerant quantum computing has to be supported end-to-end in both hardware, mid-circuit, and classical processing because the fault can manifest at any part of the pipeline, for example, Silent Data Corruption in the classical processing part. As the author mentioned, "becoming clear that we cannot separate classical and quantum parts of the program".
