and that is exactly what slices are for! ;-)
you are probably better to use `const(char)[]`, tho. like this:
// don't store `s`, as it's contents may change after exiting of
`myfunc`
// (this is what `const` implies here)
void myfunc (const(char)[] s) { ... }
...
string s = "test string";
myfunc(s); // yep, this works
s = s[2..4]; // this doesn't allocate
myfunc(s);
myfunc(s[3..6]); // or this, it doesn't allocate
myfunc("abc"); // or this, doesn't allocate
you got the idea.
Gotta save this too.

+X (typically just 1) means that you agree.
But here we just say "thanks". This "forum" is backed by an NNTP server,
so lots of the more newer concepts don't exist here.
