Sure, but in that case they are equivalent to a static function so there's no benefit of lambda other than syntax sugar.
Capturing lambdas in a language without a GC (or a borrow checker) are kinda fraught with footguns.
The benefit is that you don't have to solve one of the hard problems in computer science (naming things).
