Makes me wonder if maybe the syntax for mapping, folding and other collection operations should have a similar syntax to for instead of the current method-style syntax popular in most modern languages.

[symlinkk]

C# has a syntax called Linq Query Syntax that provides keywords in the language to do things like map, filter, and reduce.

Example:

  var queryLondonCustomers = from cust in customers
                             where cust.City == "London"
                             select cust;

I'm not a big fan of it honestly, the function style seems more consistent and easier to read to me.

https://www.pyret.org/ does it like this:

  for each(str from [list: "Ahoy", "world!"]):
    print(str)
  end

  for map(n from [list: 1,2,3]): n * n end
  # ==> [list: 1, 4, 9]

  for filter(n from [list: 1, 2, 3]):
    n >= 2
  end
  # ==> [list: 2, 3]

  for fold(sum from 0, n from [list: 4, 5, 6]):
    sum + n
  end
  # ==> 15

That sounds a lot like Python list comprehensions
