I will put together some benchmarks over the weekend. Claude Code and I
don't know PowerShell that well, but we will figure it out.

Personally, I would expect all the permutations of the standard library
modules required to be provided by my compiler vender, e.g. Ubuntu.

The thing that I think is missing from this conversation is the *ccache*
tool. That tool's optimizations are effectively broken by changes to binary
precompiled objects. Otherwise, it is capable of some incredibly perceptive
caching.
