fell free to revese it

i just wanted to note that the change had already been suggested previously, i have nothing against using it
(note that i am a collaborator, but thanks to a branch protection rule i cannot merge my own PRs without another collaborators approval)

[hasezoey]

please update the test files, see Development/Testing, see failing tests.
(preferably put those changed tests into the commits that changed them)

also it would be great if there could be a test and compile-test for the async paginate (that does not particularly need to be in this PR)

[driver005]

oke i will reverse the change to unused dsl import becuase of #134
it would be great if someone adds the test

[hasezoey]

Looks ok now, personally i would have liked if the commit messages would follow the style of past commits, though wont a problem here because i will squash it.
(i know that we currently dont have a CONTRIBUTING file)
