First, thank you very much.<br><br>
>1: print '218'.subst(rx/^18/, 3);<br><br>
Great, this works for me.<br>
It was a real effort for me to figure out how "<code>s///r</code>" works in Perl6... It turned out to have a completely different syntax, but I do miss the Perl5's version: it's so concise, and since it is like a mother language, it can't be obfuscated anyway. I hope Perl6 can still allow the Perl5's sed syntax, conforming to TMTOWTDI. :-)<br>
<br>
>2: this is supposed to work with substr-rw, but doesn't with current rakudo.<br><br>
I see.<br>
<br>
>3: Sorry, I don't even understand what this code does in Perl 5. Modifying and using a variable in the same statement is very detrimal for readability.<br><br>
I will explain these code in the next post.<br>
<br>
>4: labels and goto aren't implemented in Rakudo. You can use prompt, or for lines() { } (since lines() is a lazy list, it doesn't read all the lines upfront; this was broken in some earlier Rakudo versions, but should be fine in the 2012-12 and possibly the 2012-11 releases).<br><br>
I am using version 2012-11, and it is slurping. but I wonder is the parentheses with "<code>lines()</code>" mandatory? It doesn't seem like Perl's style though?<br>

>I can recommend hanging out in the #perl6 IRC channel, we try to be helpful and friendly (and we succeed most of the time :-).<br><br>
I will try that.
