A question for @s-perron: Is specifying `internal` for functions not the correct way? The check is getting `error: line 4: Capability Linkage is not allowed by Vulkan 1.3 specification (or requires extension)` after adding the vulkan1.3 triple and target env. Is `hidden` visibility style what I'm looking for?
