Shadows over loops

[Guest mantragora]

Hi!

So we can't have nested foreach() loops?

 

This:

int thoseNumbers[] = array(0, 1, 2);
int otherNumbers[] = array(3, 4, 5);
 
foreach(int this; thoseNumbers)
{
    foreach(int other; otherNumbers)
    {
    }
}

throws this:

Declaration of variable '__impl_foreach_index' shadows a previous declaration at line FOO

warning.

WTF?

Happy rainy day!

I remember having the same problem and it's probably a bug worth submitting, which sadly I didn't at the time

I ended up using good old for, but please submit a bug

int thoseNumbers[] = array(0, 1, 2);
int otherNumbers[] = array(3, 4, 5);


foreach(int this; thoseNumbers)
{
    for(int i=0;i<len(otherNumbers);i++)
    {
        int other = otherNumbers[i];
    }
}

interesting.  i wonder what the byte code for a foreach looks like.  is it just a glorified macro for a for loop?  that error kind of implies that it is with a hardcoded index variable.

Should be fixed in H15.
