I think ~ is assigned to regex match already?

No, see perlop 

Binary "=~" binds a scalar expression to a pattern match. 
Binary "!~" is just like "=~" ...
Binary "~~" does a smart match between its arguments.
Unary "~" performs bitwise negation
""->"" is an infix dereference operator, just as it is in C and C++.
nonassoc    < > <= >= lt gt le ge

so currently  ~> is a syntax error, you can't have unary operator bitwise-negation follow greater than operator, so  ~> is free and open for use with no possibility of confusion with anything else

Also, neither  > nor ~ nor ~> nor -> are sigils, sigils are  $ % @ * as in  $ro %sham @bo *dynamite
