It is used in ~50% of modules & looks a standard feature at this point.
This allows to achieve Zen of Text<->String & Path<->FilePath. Set of functions for Text & Path now can be formed & exported.

This explicitly states the code smell of String use left.

After making this flexible prelude setup, we are moving the custom code back into Nix.Utils, so the downstream projects do not have trouble importing Prelude module, but just use regular Nix.Utils module.

Moved function got some alteration. Reduced Lazy -> Strict marchalling. Also instead of Lazy used Strict data types, since on the conveyor that data seems to be consumed fully (which I may be wrong about).

We essentially had 2 preludes, now they are merged & allow to control what parts of
reludeare exposed.It clean-up imports quite a bit & provides a set of frequently used functions.
reludeis a pretty good prelude, but it still has flaws (for example it exposes a mix ofText&Stringfunctions, which is weird from the outside). If we want to useTextinternally - that should be it, conversion can still be needed (forbase^ GHC reasons), but at least is would be only on the IO margins (which arepreludefunctions), not 2 conversions in the middle of data flow.This setup helps to program with supplying
Texttype functions & support of stronger types.There may be a specific thing - currently, it is probably tricky to import our
Preludemodule into other projects, that can be addressed by moving stuff back intoNix.Utils& passing it throughPreludemodule, but then people would start importingNix.Utilsfrom time to time in the code base, which is Ok, since because ofPreludepassthrough - that would be rare.I needed to do this sort of merge, to align all code & project this way properly, before I do further things with it.
This is the last thing I had in mind, I plan to stop refactors any moment if #804 ever continues.
