in thread Help me not use for($i=0;$i=$#array;$i++)...Please!

This was an extremely simplified example to try and get to the core problem. In reality this is an array of arrays inside a hash. I'm looping through doing some processing and certain things should only be processed once but others should be processed multiple times. My solution was to remove them from the array after processing if they were to only be processed once.
After looking at all the great responses here I think @array = grep $_ != 5, @array; is what I want. The 5 would actually be an array reference, but I think this will work.

Thanks for all the help,
Ira.

    If you bracket it, the grep expression becomes a block. It can be as complicated as you please. If it evaluates true, $_ (possibly modified within the block) is placed in the returned array.

    After Compline,

    Update: Corrected block <-> expr terminology.
