So far nobody has complained about any of this, I'm guessing because it looks very familiar, and that was intentional. Oil takes some pains to literally look like shell + Python syntactically, with better semantics.
I noticed that a few other shells are having problems with this command/expression distinction, and I discussed it like 3-4 years ago with Ilya Sher (of NGS) and a few other people. They were also having the same problem.
For example, does / mean a path separator or the division operator? Does * mean a glob or a multiplication? In Oil, this is no problem. It's obvious depending on the context.
Though I'm interested in more feedback on this, and the latest release is available to try as always :) https://www.oilshell.org/release/latest/
The awk and make integration is still doable but not done. Awk might require a notion of "lazy expressions" or "lazy arg lists", which would be shared with dplyr-like functionality. Oil's Zulip is open for discussion on these ideas :)
