I've sent this message before, but Piers was kind
enough to point out that the CGI script I'm forced to
use to send mail does not readably format my messages,
increasing the likelyhood that they are ignored. So
here's a repost that's (hopefully) better to read.
==================================================
Somewhat random question here:
We all know how to alias things in Perl 5. The binding
operator allows aliasing in Perl 6, I understand. So,
how do we alias grammer rules? Here are my guesses.
Rules live in the same namespace as subroutines, so
you can use the &. Or possibly (because filehandles
are first class objects and formats are phhbbtt)
rule1 := rule2 with no sigil. Even if rules don't work
like this, I'd like to know if that works for subs.
If we think of &sub $scalar @array and %hash as typed
references and the sigils as disambiguating *which*
reference, then perhaps we use <> as in <rule1> :=
<rule>
We can't.
A related question - rule {..} can create an anonymous
rule, but how do we create a ref to a named rule?
