Feature request: nix repl history navigation via prefix string like fish shell

[lolbinarycat]

Is your feature request related to a problem? Please describe.
often when in nix repl you want to re-evaluate an expression. currently you have 3 options:

• press up dozens of times until you reach the expression you want
• retype the expression in full
• use ^R (clunky, and has poor discoverability)

Describe the solution you'd like
the fish shell (and several other REPLs) have a solution for this:
when pressing up with a string already entered into the prompt, instead of just going back 1 step in history, it goes back until it finds a command starting with that string.

Describe alternatives you've considered
some way to set aliases for frequently used commands via something like :alias.

Additional context
bringing nixpkgs (or whatever nix expression i am working into scope of the repl often feels tedious, expecially with rapid iterative development.

:r should help with this slightly, but not as much if you have to leave the repl to do a git command or something.
