A class without a name cannot be initialized, because it isn't
possible to define a constructor. Example:

  class {
    ... // how define a constructor?
  } x(17);

If it were allowed to use keyword 'this' for constructors, then it
would be possible to initialize an unnamed class.

If so, then it would be a good opportunity to change the default for
those constructors to 'explicit'. An 'implicit' constructor could be
declared by making use of recycled keyword 'auto'. Examples:

  class {
    ..
  public:
    this(int a)        {} // explicit
    this(int a, int b) {} // explicit
  } x(2), y(7, 13);


  class MyString {
    ..
  public:
    auto this(const char* s) {} // implicit
  };


So far I can't think of any collision with the other meanings of
'this' and 'auto'. Can anyone?

Would it be a language change of interest?
