In the afternoon Esme and the children continued with the igloo project. Later in the afternoon I helped out as well.
In the evening we managed to close the roof which was not an easy task. Luckily I had found a large piece of frozen snow that we could use as a kind of support for four more bricks. After that we filled up the holes with powdery snow.
Haskell is, in my opinion, a far more well designed and coherent language than JavaScript. However, it's also an old language with some historical baggage. In many ways, it's a bleeding edge research language that sometimes includes...half-baked features. Due to an inconsistent set of rules around backwards compatibility, it will sometimes break code every six months, and sometimes keep strange decisions around for decades.
