I'm torn. Not about the conciseness of the language overall, but about using symbols vs. names. I do see how the symbols make things more concise, less clutter, and can even make it easier to grasp a piece of code if you are deeply familiar with them[1]. On the other hand, there might be a limit. I do know how it is to use the Haskell lens package only occasionally, and then having to lookup again what the operators…
In languages like K or APL, the combination of symbols is the actual definition.
