There is a discussion about introducing "descriptive" diagnostics of the same style happening on the Swift Forums at the moment - https://forums.swift.org/t/pit

  This is the diagnostic produced for similar example using new diagnostic architecture: error: binary operator '+' cannot be applied to operands of type 'String' and 'Int' _ = "a" + 1 ~~~ ^ ~ note: overloads for '+' exist with these partially matching parameter lists: (Int, Int), (String, String) _ = "a" + 1 ^ note: candidate expects value of type 'String' for parameter #2 @inlinable public static func + (lhs: String, rhs: String) -> String ^ note: candidate expects value of type 'Int' for parameter #1 public static func + (lhs: Int, rhs: Int) -> Int ^
