Add the ability to set up variables on the describe block about purescript-spec

[owickstrom]

Could this be a variant of #43, if we separate beforeEach/before, and afterEach/after?

[Risto-Stevcev]

I guess it depends on how it's implemented. If before and after look similar to it, then the variables wouldn't be in scope to use it in this way

[owickstrom]

Yes. I'd like for before and after to make it blocks be functions instead. For every before/each you nest, the it blocks get a new argument:

describe "some state" $ before readRef $ before readArray $ do

  it "should have this property" $ \ref array -> do
    ...

  it "should have that property" $ \ref array -> do
    ...

Not sure the current design makes that very simple to implement, but I think it would be very nice to have. :)

To me, hspec's hooks API looks like a good idea to mirror to achieve this: https://hackage.haskell.org/package/hspec-2.4.3/docs/Test-Hspec.html#t:ActionWith.

I don't think it would be terribly hard to make this happen. I wish I had the time to tinker with this, looks like a fun task

[owickstrom]

@felixSchl Thanks, will have a look at it.

I hope I can find some time, too. It does not look very bright in the coming week. :/

[owickstrom]

Still, I have no time to work on this. Anyone who wants to give it a shot?
