Recently the encoding.safeDecode stopped working for some of my existing
code. This example outlines the issue:
import std.encoding;
void main(string[] args) {
auto e = EncodingScheme.create("utf-8");
auto a = new byte[100];
e.safeDecode(a);
}
Results in:
Error: function std.encoding.EncodingScheme.safeDecode (ref
const(ubyte)[] s) const is not callable using argument types (byte[])
Isn't this an error in the compiler?

No, this is a bugfix. The operation is unsound:
immutable(ubyte)[] foo(ref const(ubyte)[] s){
auto r = new immutable(ubyte)[1];
s = r;
return r;
}
void main() {
ubyte[] x;
immutable(ubyte)[] y = foo(x);
static assert(is(typeof(y[0])==immutable));
auto oldy0 = y[0];
x[0]=oldy0+1;
assert(oldy0 == y[0]); // fail
}
The functionality is not going away; You will be able to use inout for
the same purpose once my enhancement request gets implemented:
