My understanding is that Spago puts all build products into the output sub-directory. This includes both all the dependencies and the project code itself.

I would like to speed up continuous integration by caching this directory. Is it expected by design that exactly the updated code will be re-built in the presence of output filled with earlier build products?

Also, would newer versions

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.
