cat > bug.d << CODE
import std.algorithm : move;

int* escapeLocal() @safe
{
    int var;
    scope int* p = &var;
    return move(p); // should error
}

void test() @safe

    auto p = escapeLocal;

Reduced example not specific to scope classes, seems like move should take it's
argument as return scope, no?
