The researchers are now investigating whether a similar gut microbiome and brain activity pathway exists in humans, and whether it also contributes to age-related cognitive decline. Importantly, vagus nerve stimulation is approved by the Food and Drug Administration as a treatment for depression or epilepsy and to aid stroke recovery. The researchers are also interested in developing ways to non-invasively monitor, and perhaps even control, the activity of peripheral neurons to affect memory formation and cognition.
However, for the specific problem of generic programming the trade-off doesn't hold up. The alternative—type classes, as in Haskell, or traits, as in Rust—gives ad hoc polymorphism (functions that behave differently depending on the type) while preserving parametricity. We get specialisation where we ask for it, and reasoning guarantees everywhere else. It's extensible, too: anyone can add a new type to an existing type class. Zig's comptime dispatch is not.
