Re: Test scalar refs (not values) in deeply nested structure

Hi Rolf,

So ... you have:

my ($pos1,$pos2)=("a","a");
[download]

and you want a test that will report that \$pos1 and \$pos2 are "different".
I think a simple cmp_ok(\$pos1, 'eq', \$pos2, "should fail"); will fail.
The bit I haven't quite grasped is the circumstances under which \$pos1 and \$pos2 should be considered the same.
What values do you assign to $pos1 and $pos2 such that this test should report that \$pos1 and \$pos2 are "the same" ?

Cheers,
Rob

>The bit I haven't quite grasped is the circumstances under which \$pos1 and \$pos2 should be considered the same. I am also confused since your example is not nested at all, i.e., I don't think the scalar reference itself is considered nested since you're pointing to two different memory structures (addresses). Do you have an actual nested data structure, LanX?	[reply]

> The bit I haven't quite grasped is the circumstances under which \$pos1 and \$pos2 should be considered the same. Never, it's a false positive. (Or to be more precise only if both are aliases, hence `\$pos1 == \$pos2` , but which can't happen in my use case ) They are not nested in the OP because it's the easiest possible demo. See here Re: Test scalar refs (not values) in deeply nested structure (workaround) for more test cases.
