Currently, most GHC API tests are not run on 'make fast', ostensibly because linking against the GHC API can take a while. I propose that change this, and run GHC API tests by default. Reasons: 1. The GHC API is closely tied a lot of internal structure of GHC, so it's very easy to make a change, track it through the rest of the compiler, but forget to update the tests/documentation. 2. We can boost this into poor man's testable documentation. The idea is to duplicate all GHC API examples in the manual in the test suite, and have a comment on all of the examples asking the developer to update the manual. (Or we could automatically extract the snippets from the manual, but that's work and this I could do in a few minutes.) 3. I don't think running these tests will add that much extra run time to the test suite; certainly interactively the time spent linking is unnoticeable. Let's set a one week discussion period for this proposal. Thanks, Edward
