Old D code (from the 32-bit only days) used to do this

printf("Hello %.*s\n", "segfault");
So it relied on both the length and pointer being passed.
Unfortunately
this was done quite a lot, so simply changing the rules so
string
literals get passed to C varargs as pointers would silently
(and
horribly) break this code.
(isn't there a proper string type in D2?)
nope, it's just an ordinary slice (although the fact that it's a
slice of char does make it a bit special w.r.t. unicode)
The compiler doesn't even know about the name string, it's just
defined here:
