The feature gate for the issue is #![feature(const_assume)].
It makes core::intrinsics::assume usable in const contexts.

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

@tesuji Do you want to stabilize the feature?
I was asked to use assume in const context here: #119452

WG-const-eval has confirmed that this is fine: #119452 (comment)

Feel free to send in a PR flipping the stability attribute. It's an unstable intrinsic so we aren't really committing to anything.
