This code will trigger SA1119 (Statement must not use unnecessary parenthesis) while those parenthesis are necessary to make the expression negative.

if (!(someVariable is TypeA typeAVariable))

On the other hand, if we use only type check without pattern matching, the error will not pop up:

if (!(someVariable is TypeA))
