I think this is the first step of a long and difficult way.

I guess such bugs will be detected (in safe code only!) after the
implementation of: http://wiki.dlang.org/DIP69 Currently

Hi!
I thought at least in safe mode this code will not compile or I
get warning:
byte[] func() @safe {
byte[1024] buffer;
return buffer[0..3];
}
void main() {
auto b = func();
b[0] = 1;
}
But no any error. Dlang do not catch this?
WBR,
Fyodor.
