The expander collects defmacros from the prelude and from the file being
compiled. Not from an imported package, and the reason is an ordering one:
Load learns a package's imports by parsing it, so reaching a package's macros
would mean resolving that package's own imports over Forms, before Load runs.
That is a second import resolver, and it is a bigger thing than this lane.
Refused by name, which is the rule that caught the two misparse bugs. Left
alone the call arrives at the checker as an unknown name -- true, and no help.
Refused where the defmacro is written rather than where it is called, because
that is where the fix goes.
The check has to sit in Load's read, because that is the only place that can
see one: by the time Parse is finished a defmacro is an ordinary Ast.Defn and
the word is gone.
Measured while here, since a prelude that grows a defmacro is a cost every
program pays or does not:
- A build of a program that names no macro: 50ms, the same as before. The
pass scans the top level, finds nothing, and no compiler runs.
- A program that calls one: 310ms the first time, 70ms after. The 240ms is
the clang driver building the macro module; it is cached under the object
cache, keyed by the prelude's source and the file's defmacros, so it is
paid once per change rather than once per build.
- A hello-world's binary carries exactly one symbol out of all of this:
flan.gensym-n, eight bytes. Reach.link drops unless, form-cons, form-nil,
form-append, form-rest and gensym, because nothing reachable calls them.
