out the "Clone" method. Why? o.O
Because it calls constructor and fails? I've done substitution
for you:
this(const vec!(float,2) values) {
foreach (index, val; values) {
this.values[index] = cast(T) val;
}
}
No big wonder.
I'd try to fix Clone to:
{
vec!(T, dim) tmp = void;
tmp.values = this.values;
return tmp;
}
Then temp is empty/null and you cannot assign anything to it.
Furthermore temp would get a reference to the original array.
And why it fails?
As i see, Clone calls this opCall method:
[code]
static vec!(T, dim) opCall(U, ubyte dim)(const vec!(U, dim) v) {
return vec!(T, dim)(v.values);
}
[/code]
A simple workaround is to write
[code]
this(U...)(U values) {
T[] temp;
foreach (val; values) {
temp ~= val;
}
foreach (index, val; temp) {
this.values[index] = cast(T) val;
}
}
[/code]
instead of
[code]
this() {
foreach (index, val; values) {
this.values[index] = cast(T) val;
}
}
[/code]
But that seems weird to me.
