In the case of 'x in y', 'x' and 'y' are both variables, but in the
case of 'x has y', 'x' is a variable but 'y' is a name.  I think that
could be confusing.

On the other side of things, it seems this could be introduced into
the language without making 'has' a keyword--no syntactic rules
currently use concatenation.
