Personally I don't mind unusual syntax. I do find it a bit problematic that programming languages seem to select syntax almost at random, or at least they don't tend to spend a lot of time explaining it [0]. A lot of special characters can quickly become less pleasant with a non-English keyboard however. Especially if the syntax is hard to predict (with for example autocomplete).
