What do you mean by *any* member?  If any is an identifier typed
metavariable then that would get any immediate member.  But maybe you want
something like

<+...ctl->any...+>

that will match anything that has ctl->any as a subexpression?

It may be necessary to put this in parentheses to address parsing issues,
but the () won't need to be present in the matched code.

You could also use

assignment operator aop;

rather than =, to also match += etc.
