    (ffi/calling-conventions)

    Get an array of all supported calling conventions on the current 
    architecture. Some architectures may have some FFI functionality 
    (`ffi/malloc`, `ffi/free`, `ffi/read`, `ffi/write`, etc.) but not 
    support any calling conventions. This function can be used to get 
    all supported calling conventions that can be used on this 
    architecture. All architectures support the `:none` calling 
    convention which is a placeholder that cannot be used at runtime.
