Languages with one user

I don't usually read the reddit comments on my posts, because the signal-to-noise ratio is not that high, and because the "Arcane totally doesn't get it" comments are discouraging. But this means I miss some good ones. Xach said:

When a language has only one user, who is also the implementor, badly interacting patterns don't always become obvious. The tendency is to automatically avoid problematic things without thinking about it.

Good point. I will remember this next time I start to say "...but it doesn't seem to be a problem in practice."

Mainstream at last!

Functional programming is slowly becoming popular. Yesterday I heard someone refer to Haskell as a "mainstream language". ^_^
