I played with a similar idea of converting a plist to something you can
call to access values at
https://kitchingroup.cheme.cmu.edu/blog/2017/04/16/A-callable-plist-data-structure-for-Emacs/.
It did end up as a macro, but no eval required. It never made it past that
post, but it might have an

Well, let-alist is for alists, not

Life has its moments
This is fun, thanks John. I really like the plist version put would also
like to loop through the variables in a let statement somehow.
I think what I'm missing is the equivalent of a javascript implicit
destructuring construct:
let { } = object;
which will define new variables prop1, prop2...
You don't really need a macro for this I think. I see it leads to pretty
clean looking code, but as you noted at the expense of edebuggable
functions. I don't think you need the lexical-let in your macro though.
With empty arguments I am not sure it does anything.
Here are some other approaches

I don't totally understand what you are trying to do here. If this were
Python, it sounds like you want some kind of class that stores a variable
and reuses it several different functions? Something kind of similar to
that in elisp is a closure, which is like what you described. For example,
here,
I have a number of convenience functions define to help me with grading
assignments. As I go through the semester, i update all of these functions
modestly so that they'rehelpful for grading the current assignment.
I big chunk of these simple functions is taken up just declaring variables
