Add an "any number of" wildcard about gogrep HOT 3 CLOSED

Note that $x* is also valid Go, so I'm not sure that works any better than $x... (which was also my first thought).

Perhaps make the suffix significant only if it isn't separated from the $x by any whitespace?

Ah, you're right. Yes, I was thinking with whitespace in mind, forgetting about $x *string and others.

I'm trying to come up with some other symbol that can't possibly form valid Go, while still being readable and intuitive. Can't find a better one for now.

Both expressions and statements should be working now. It doesn't record previous nodes yet though, so $x* will behave like $_* for now.
