 Fix: You must use 'all ()' on the command line.

-echos, and those in stdlib should run silently (except if debugging).
-Maybe we should have a quiet keyword to indicate this?
+Deleting target files if goals is interrupted, but only if the
+timestamp changes (what about non-*files?).  Also: atomic code.  This
+will delete the target if the code doesn't run to completion.  (make
+doesn't do this, but probably it should).

+Parallel builds: On failure, wait for other jobs to finish.

+Conditional sections (same as "ifeq" etc in make).

+Let within functions and goals, eg:

+Unclear if this would be helpful or not.

+Implement more make functions, see:

+Make re-execs itself if the Makefile (or any include) changes, and
+goals should do something similar.  See:

+Code should be an expression, eg this ought to work:

+Infinite loop when you have this goal:
+goal pod2man (page, section) = "docs/%page.%section" : "docs/%page.pod" { ... }
+This is caused by %section matching "pod" so the rule is called
+again, even if the local file docs/%page.pod actually exists.
