I have three lazy ranges tied together in a foreach loop like
so:
Item[] items; // An array of Item-struct
foreach (item; items.range1.range2.range3) {
// ...
}
The funny thing is that when I run the foreach loop it does
everything in reverse. So I changed it to
foreach (item; items.range3.range2.range1) {
// ...
}
And now it works as expected. I've never had such strange
behavior and have no clue what could have caused it. In all
my other ranges it works from left to right 1. step, 2. step,
3. step and not from right to left.
Can you post some code?
And it is also circular. range3 sends it to range 1 again I
must have screwed it up somewhere. Everything is ok, if I do it
step by step:
foreach (item; items.range1) {}
foreach (item; items.range2) {}
foreach (item; items.range3) {}
Has anyone ever come across a bug like this? Each range works
fine on its own. When I tie them together, they go upside down
and in circles. Weird. Maybe I can extract some test code.
How strange. Sorry, without seeing some code I doubt it's
possible to understand what's happening.
