! This works, but since it isn't optimised, alien-invoke doesn't work.

: SLFunc:
    CREATE-WORD dup
    '[ 0 <ulong>
       [ "void*" "libMagickWand" _ { "char*" "ulong*" } alien-invoke ] keep
    ]
    define ; parsing

! Trying to declare effect

: SLFunc:
    CREATE-WORD dup
    '[ 0 <ulong>
       [ "void*" "libMagickWand" _ { "char*" "ulong*" } alien-invoke ] keep
    ]
    (( pattern -- pnum plist ))
    define-declared ; parsing
