I recognise that autocompletion is not very high up in your personal list
of criteria of what's important in a programming language; I do have other
reasons that I think nmigen's current design is not the best, but it's
mostly a whole lot of individually insignificant things that pile up and I
can't remember most of them at the moment.
I highly recommend trying out a autocompletion plugin for vim, such as
youcompleteme. It works for python, rust, c/c++, and many other languages.
It can suggest completions from the standard libraries, from
import/use/#include statements, class members and many other things. They
usually work better on statically typed languages since it's easier to know
the types then. You could think of it like tab-based completion on the bash
command line but much more powerful.
I started programming using Quick Basic and Turbo C++ on DOS so I have a
lot of experience using ides that were just slightly more advanced than
nodepad (which is slightly better than cat as an editor -- aka don't use it
if you have any slightly viable alternatives (though I hear it's been
getting better -- LF-only line endings support was recently added)) with a
built-in command to compile code.

I use the command line most of the time for file management as well.

Currently it's at least any ide that supports the Language Server Protocol.
Python has a language server that can do much better than that: pyls.

I'll be just fine with nmigen, just will need a bit more time to get used
I have kinda wanted to write a decent (records + generics/templates +
turing complete compile/generate-time code generation + static typing) HDL
for a while anyway. I had started writing one from scratch last year (
https://github.com/programmerjake/cpp-hdl), but got bogged down in writing
compile-time code generation and a template system like C++'s. If I have
the HDL be an embedded language in rust (like nmigen in python), rustc
would take care of the hard parts for me.
I'm planning on eventually writing the Rust HDL, but not as part of our
project (though would be happy to work on it as part of our project).
