OK, I have never felt the need of such extra flexibility in my D programs, so I trust your judgement.

Every time a a semantic hole is left in a language (and this is a little hole), you have to pay a price, in terms for example of:
- less easy to understand error messages (the currently generated error message is not easy to understand and I think it's wrong, because in that program the four names are distinct, there is no duplication);
- less simplicity for the D newbies to learn the language, because to learn something faster you need a strict teacher;
- possible bugs caused by side effects of the semantic hole (because semantic holes often create semantic loopholes).

In Delphi the "main unit" of a program is denoted with for example, at the top:
program Project1;
