Hi,

I don't know what happens and where in the code, but... Anyway, it's 
strange... I have this code and input.tpl:

--------------- 8< -------------------

rule sp {
     <[ ]> 
}

rule id {
     <[a..z]> <[a..z0..9]>+
}

sub do($match) {
     say $match[0];
     return "+";
}

my $template=slurp('input.tpl');

$template ~~
     s:g!
     [ \< server \: (<id> ) [<sp>+ $?id:=(<id>) <sp>*=<sp>*"(<-["]>*)"]* 
<sp> * \> (.*?) \<\/ server \: $0 \> ]
     |
     [ \< server \: (<id> ) [<sp>+(<id>)<sp>*=<sp>*"(<-["]>*)"]* <sp>* \/\> ]
     !{ do($/) }!;

say $template;

--------------- 8< -------------------

text

<server:foo /> 

<server:huh /> 

text

<server:boo>  inside <server:huh /> inside </server:boo>

text

--------------- 8< -------------------

Running it several times, one time works: matches and replaces </>  
things to +-es, one time it not works... Randomly. Where should I send 
these kind of bugs?

Bye,
   Andras
