gather { if $xy.was_taken { ... } }

[Gilbert R. Röhrbein]

Hi,

I'm new to Perl 6 (and perl).
Is there a way to check inside a gather-block if something was allready 
taken? I thought it would look like one of the following, but it doesnt 
work on my pugs 6.2.13.

gather
{
   for 1..100
   {
      take $_ unless @_.contains(42)
   }
}

gather -> @rray
{
   for 1..100
   {
      take $_ unless @rray.contains(42)
   }
}

merry christmas,
   Gilbert.
