The browser navigate the current page (from https://wryk.github.io/purescript-halogen-realworld/#/login to https://wryk.github.io/purescript-halogen-realworld/?#/login) when logging in, bypassing login app behavior and re-displaying the same login form. I can consistently reproduce this bug on both submit button click and enter keypress with Firefox 79 and Chromium 84 on the url without the empty

I'd ❤️ to have an analog of stack's script feature:
https://docs.haskellstack.org/en/stable/GUIDE/#script-interpreter
https://www.fpcomplete.com/haskell/tutorial/stack-script/#running-a-script

Example:

$ head myscript.ps

outputs:

#!/usr/bin/env spago
-- spago script
import Prelude
...

then

$ chmod u+x myscript.ps
$ ./myscript.ps

Not sure what this would entail yet, but it would likely be a better way to reduce some of the boilerplate of opening an issue.

Currently compiling Data.Either.Nested takes about 10 seconds. It emits about 84k lines of code! So we should (a) investigate optimization passes to remove the lines to output and (b) make it run fast even when generating large files like that.
