flan--special was three kinds of name in one list: the forms the parser
dispatches on, the functions the compiler provides, and the words that
stand for themselves. Drawing push like let said they were the same kind
of thing. They are three lists now, each read off the file that decides
it, and the two names in the old one that are not in the language at all
-- cast and none -- are gone with it.
What else had been missed: dyn, Allocator, Vec, Map, Fn, int and float
were not types, $t was not anything, handler-case was not a keyword, a
comma was not whitespace, & was not a name character -- which a macro's
parameter list needs, now that it destructures -- imenu had no heading
for a macro and none for the four dispatch forms, and a labelled loop
indented its body under its own binding vector, which loops.flan has
four of and would have said.
Then the second half. The defs op already told the editor what every
name is, and only completion and eldoc were listening, so a macro you
defined looked exactly like a function you defined. It carried no macro
kind to listen for and could not have: a macro is a defn by the time
there is a program. So the op answers with one -- keeping the location
off the defn it drops, so M-. still goes there -- and with the type
names, read off the checker's environment, since an enum is an i32 and
an alias is gone by then.
The editor draws them by kind, after the static rules and never over
them: a program defining its own length does not get to repaint the
builtin. A hash table and a matcher rather than a regexp of every name,
rebuilt when the cache is and not when a key is pressed. With no session
the rules come off and the buffer is what it always was.
