The problem
-----------
String literals in D are a little bit magical; they have a trailing
\0. This means that is possible to write,
printf("Hello, World!\n");
without including a trailing \0. This is important for compatibility
with C. This trailing \0 is mentioned in the spec but only
incidentally, and generally in connection with printf.
But the semantics are not well defined.
printf("Hello, W" ~ "orld!\n");
If every string literal is \0-terminated, then there should be two \0 in
the final string. I guess that's not the case and that's actually my
preferred behaviour, but the spec should make it crystal clear in which
situations a
string literal gets a terminator and in which not.
The \0 is *not* part of the string, it lies after the string.
It's as if all memory is cleared, then the string literals are copied
into it, with a gap of at least one byte between each. The 'trailing 0'
is not part of the literal, it's the underlying cleared memory.
At least, that's how I understand it. The spec is very vague.
