Hi,
while writing a preliminary p6explain, I wondered if the following
should work:
my $text = "aBc";
$text ~~ s/B/{ "C"|"D" }/;
say $text.values; # aCc aDc
This would be extremely handy for p6explain, as I'm currently parsing a
datafile which looks like...
+
Standard mathematical infix operator.
@infix_ops
+ - * /
[EMAIL PROTECTED]
Reduce metaoperator.
Think of a join on the syntax level.
I could then do something like this:
# $rule is '[EMAIL PROTECTED]'
$rule ~~ s/[EMAIL PROTECTED]/{ any split " ", %rule{'@infix_ops'} }/;
copy_contents_to $rule.values;
Comments?
