I use ldc2. No dip flags here.
---------snip---------
import std.stdio:writeln;
int [] fun() @safe { // N.B.: need @safe
int[3]s=[1,2,3];
int[] r=s;
return r;
}
void main() @safe { // N.B.: need @safe
writeln(fun()[0]);
}
---------snip---------
LDC output:
---------snip---------
$ ldc2 -dip1000 /tmp/test.d
/tmp/test.d(6): Error: scope variable `r` may not be returned
---------snip---------
T
So I put everywhere @safe ?
When not ?
