All compile-time strings should be both 0 terminated and implicitly 
convertible to immutable(char)*. I think there are some cases that 
aren't, but I don't remember all of them.

But the question above is still unanswered -- writeln receives a string 
as an immutable(char)[], and doesn't know that it's from a literal.

For example, if writeln blindly assumed that all immutable(char)[] were 
string literals, that it could pass to puts, this would be a problem:

writeln(somestr.idup);
