[Israel.pm] How to remove elements according to a filter from an array

[Yossi Itzkovich]

 Thanks, the man page seems promising.  But I was surprised to see that delete (and exists) work for arrays, I always thought they were there for hashes only. Is it something new, or just my ignorance ?

Hi

See perldoc -f delete.

4 example (Untested)

foreach $index (0 .. $#ARRAY) {
        delete $ARRAY[$index] if (criteria);
    }

Hi,

Assuming I have a big array, and I want to remove elemnts according to a
criteria, how do I do it ?
Please note, I am not asking about getting a new list of elements that
passed the filter (like grep does), but removing the items from the
original list.  For a big array (and assuming that arrays are
implemented with linked list (is it ?)), then removing items from the
original list might be much faster.
