=head1 DESCRIPTION

This module provides simple

d object in a smart match will cause an error
unless C<fallback> is true or the object overloads C<~~>, in which case the
matcher sub will not get a chance to work anyway.

Boolean, string, or numeric), or when it is an explicit argument of
a C<~~>.  Otherwise it's a rule constructor.  So this:

no longer does the match 

 of C<@array>, in order.

If C<$indextest> is provided, only elements whose indices match
C<$index ~~ $indextest> are iterated.  (To select on values use C<grep>.)

What is returned at each element of

 as C<%hash> doesn't change.

If C<$keytest> is provided, only elements whose keys evaluate
C<$key ~~ $keytest> as true are iterated.

What is returned at each element of the iteration varies with fun

as literals

[Update: C<< <> >> is no longer the input operator.  And C<=~> has been
replaced by C<~~>.]

which in Perl 5 we'd have to write as:

        # Perl 5
        my $target = <>;             

     <appendline>+
              { @$appendline =~ s/<in_marker>/</;

[Update: Smartmatch is now C<~~>.]

                @$deleteline =~ s/<out_marker>/>/;
                let $0 := "${to}c${from}\n"

   $str =~ m{ /\* .*? \*/ }xs;

        # Perl 6
        $str =~ m{ /\* .*? \*/ };

[Update: Use C<~~> now.]


=item Remove leading qualifiers from a Perl identifier

        # Perl 5
        $ident =

will return 0 and issue
a warning.


=item pack

 our buf8 multi pack( *@items where { all(@items) ~~ Pair } )
 our buf8 multi pack( Str $template, *@items )

C<pack> takes a list of pairs and formats

me,0,1);

Optionally, you can use substr on the left hand side of an assignment
like so:

 $string ~~ /(barney)/;
 substr($string, $0.from, $0.to) = "fred";

If the replacement string is longer or sho

nite strings in
parallel, though that seems a bit scary.

[Update: The C<=~> operator is renamed C<~~>, and it doesn't automatically
"any-fy" an array anymore, so we could pretty easily make it work o

 backtrack over C<< <cut> >>, the entire match
will fail.)

[Update: Now we can just say C<<@lines ~~ s/^.*? \n**{2...} //>>.]

=head2 RFC 110: counting matches

I think we can avoid using any options

ingly, that can also be written:

    / <( _/\d+/ =~ 1..10 )> /

[Update: That'd be C<< <?{ ~/\d+/ ~~ 1..10 }> >> these days.]
