struct S
{
bool b = true;
bool test()
{
if (!b) // note: must be a check, not 'return b;'
return false;
return true;
}
}
struct Wrap
{
int i;
alias i this;
S s;
}
void main()
{
{
Wrap[int] wrap;
wrap[0] = Wrap();
wrap[0].i = 0;
assert(wrap[0].s.test()); // ok
}
{
Wrap[int] wrap;
wrap[0] = Wrap();
wrap[0] = 0; // note: using 'alias this' to assign
assert(wrap[0].s.test()); // failure
}
}
