We now continue deep completion search across function calls. The function must take no arguments and return a single argument. For example, when completing "fo<>" you might get candidates such as "foo.bar().baz()". Previously we would stop searching for deep completions when we hit a function call. For example, we would stop at "foo.bar()", never finding "foo.bar().baz()". At the time I was worried about the search scope growing too large, but now that we dynamically limit the search scope there isn't much left to worry about.
