I was more thinking of C# where "=>" is the closest thing I can think of to "function".

There is Func<T> - that's a delegate type.

I verbalise that as "goes to". In the case of, say,

  things.Select(thing => thing.Stuff);

I verbalise the brackets as "thing goes to thing dot stuff".

“Goes to” is what Prof. Elsa Gunter teaches in the PL theory class at Illinois

Something like (x, y) => x + y can be verbalized as "lambda of x and y producing x plus y".
