in reply to Golf: Seven segment display

Better approach:

sub w{for$;(-2..0){say map{substr'   _ _|_  |_| |',2*ord(('u$SR,Z]dmj'
+=~/./g)[$_])>>-3*$;&14,3}split//,$_[0]}}

    Applying the ...=~/./g trick (which you already used once inside the map) again:

    sub w{for$;(-2..0){say map{substr'   _ _|_  |_| |',2*ord(('u$SR,Z]dmj'=~/./g)[$_])>>-3*$;&14,3}$_[0]=~/./g}}

      I think my idea is a "cul-de-sac" but this is a little bit shorter (7 char.). 
      sub w{for$;(1005,924745596,341831533){say map{$;>>$_&1?/../?'|':_:$"}m
+ap{$_+20,$_,$_+10}$_[0]=~/./g}}

        a few obvious optimizations:

        say map$'&2**$_?$_>9?'|':_:$",map{2 .$_,$_,1 .$_}split!//,"@_"for 1005,924745596,341831533
