Good catch, but the whole implementation is annoyingly inconsistent.

I thought I could make this more obvious by implementing functions like nodege(), noflip(), and noflop() to write something like

grep { noedge(/DBIC/ .. /DANCER/)  }@list;

but try guessing which magic behavior hinders that:

  DB<52>  @list= ("a".."c","DBIC","A".."C","DANCER","a".."c");
 
  DB<53> sub ff { print $_[0]}
 
  DB<54>  grep { ff(/DBIC/ .. /DANCER/)  } @list;
0000000000
  DB<55>  grep { my $x=(/DBIC/ .. /DANCER/); ff($x) } @list;
12345E0

Of course I could also use something like compiled regexes for EDGE, FLIP, FLOP to be able to type something like:

grep { (/DBIC/ .. /DANCER/) !~ EDGE  } @list;

but that doesn't seem to be trivial, too :-(

Thanks anyway!

Cheers Rolf
