After taking a closer look at the code, it appears my case changes were
still in place. Setting it to a handle does indeed work, thanks for the
help, and sorry for being that obtuse.

Hello,
Did you actually try it? I know that that can make the difference
between runtime error and no runtime error. I thought it was kind of
odd too, but it is usually bad practice to pass an object by value
anyway. If you're worried about the object changing, you might be able
to write it as "const stat@ other".
I really think that is the problem.
This code gives me a runtime error:
"
class stat
{
int percent;
int opCmp(stat other)
{
return percent-other.percent;
}
}
stat[] stats;
void main()
{
stats.sort_descending();
}
"
And this code doesn't:
"
class stat
{
int percent;
int opCmp(stat@ other)
{
return percent-other.percent;
}
}
stat[] stats;
void main()
{
stats.sort_descending();
}
"
Best,
Aaron
