></p><p>You have several options. Antik shadows '* (along with other mathematical symbols) and an unfortunate side effect is that it affects other uses of the symbol '* in cl. So, you can just use cl:* (i.e., put the explicit prefix in). That should always work. There is a symbol macro that defines 'antik:@ to cl:*, so using @ should work. I'm not sure if there's a way to unshadow a symbol, but you can do something like <br></p><p>(setf antik::*antik-user-shadow-symbols* (remove '#:* antik::*antik-user-shadow-symbols*))</p><p>and then make a new package using antik:make-user-package, which will have all the use-package and shadowed symbols except *. If you do this, be careful to use antik:* everywhere you mean Antik's multiply, otherwise it will assume cl:*.<br></p><p dir="ltr">Liam</p><p dir="ltr">
