Is there a way to detect OS in fish shell akin to the OSTYPE variable in bash?

Question

Right now I'm forced to resort to using uname to get the operating system name and it works. But in bash there is the OSTYPE environment variable that is automatically set and I was wondering if there is something similar.

From the fish user documentation it seems that the canonical way to execute code conditionally depending on the operating system type is using a switch statement with the uname results. See example:

switch (uname)
    case Linux
            echo Hi Tux!
    case Darwin
            echo Hi Hexley!
    case FreeBSD NetBSD DragonFly
            echo Hi Beastie!
    case '*'
            echo Hi, stranger!
end
