The binop stuff you can certainly use freely, the X macro stuff is quite well known so I guess that it's also fine to use. I certainly won't be claiming any copyright on the code I shared =) My personal preference for licensing is one of the BSD or MIT licenses, I'd rather see things of mine used to makie the world a better place than force people to share what they've done with it.
