woa 1 confusing error message

[trufae]

[0x00000000]> woa 1 Invalid word size. Use 1, 2, 4 or 8 [0x00000000]>

also it will be good to use wo+ and wo- instead of woa and wos imho. not to say we can pass the blocksize as 2nd argument or handle it as its done with wo2 wo4... like woa2 1 instead of having to pass an hexpair string
