You probably don’t like this:

  String string = “String.com”;

Imagine if instead you could write:

  w̲i̲n̲d̲o̲w̲* window = new w̲i̲n̲d̲o̲w̲(...)

(that's the original ALGOL 60 reference language syntax, for the curious; although it didn't have user-defined types, so it was keywords that were underlined)

Then there's the Smalltalk approach:

  aWindow := Window new ...

You don't need case sensitivity for that.
