There are as other have already pointed out a number of very signficant  
conceptual differences.
If you want to ignore them you should prefer a less strongly typed  
language.

That said is there any reason we couldn't have an implicit (possibly user  
defined) cast to array when
no other implicit casts apply?

i.e.

T[] opImplicitCast(T a) {
   return T[](a);
}

This still wouldn't permit 'a' ~ 'b' so long as there is a valid meaning  
for  int~int
but it would be useful in other places. Thinking about it, it could  
already be built-in
I can't honestly remember.

void myFunction(foo[] A);

myFunction('a') --> myFunction(['a']);
