Contribution:tmvar not clear enough

[rlaemmel]

As it happens, I was just looking at http://101companies.org/wiki/Contribution:tmvar and I am not so convinced about the usefulness of this implementation or perhaps the motivation doesn't reach me well enough. I guess we might need to find a better motivation, better use of TMvars, perhaps subject to a revision or better use of the feature model. BTW, I guess http://101companies.org/wiki/Contribution:mvar is Ok.

Thomas, could you please think a bit about it?

Later, we discuss it during the scrum eventually.

Ok, as we are finishing our first round of cabalization with this issue standing, we leave this contribution untouched. So Thomas, at some point, you would need to look into this contribution and then also cabalize. See the README.md at the top of 101haskell for the deal.
