bug: compilation panic: cairo-lang-lowering IndexMap: key not found #7095
Description
Bug Report
3e611b5
Cairo version:
Current behavior:
With the changes made in #7094, the code no longer compiles, and panics instead of succeeding (or failing) compilation.
I'm unsure what exactly causes the bug - will try to give a MRE when I can.
related code:
#[inline]
fn count<+Destruct<T>, +Destruct<Self::Item>>(
self: T,
) -> usize {
let mut self = self;
Self::fold(ref self, 0_usize, |count, _x| {
count + 1
})
