I did not know they say the same thing about programming languages.

Based on his comment, I did not think that he is proficient in them, but that he has used them, which is fair enough, so have I, sans all the ones tied to either Apple (Swift) or Microsoft (C#).

I have some projects in Haskell just for curiosity's sake, and because what I wanted seemed like it would be nice in Haskell, and it indeed looks quite elegant to me, for this one particular project. Haskell is not a language I would use generally. OCaml is.

You are correct. I am only highly proficient in a few of them. The others are ones that I have used for varying sized projects for varying reasons, but I only learned the subsets I needed for my purposes. I would say my ability in the others in my main list varies within the low to intermediate range of proficiency.

Yeah, same here. This Haskell project is nothing serious, it just prints you the difference in time between two dates. I thought the Haskell implementation would look nice and it did. I initially made it in bash but I realized this is much more complex than what bash can handle. I had to calculate for particular calendars among a lot of other things. I think it works, more or less, however.
