Removing an item from a list

[David_Kalnins]

Hi all,

I was wondering if it was possible to remove an item from a list whilst one
is repeating over it with a foreach statement. For example, I was hoping
that the following code fragment would do this - but instead it does
exactly what I told it to do :) That is it leaves the item there but with
an undefined value.

my @list = qw ( alpha beta omega );

foreach (@list)
{
    /b/ && undef($_);
}

foreach (@list)
{
    print "$_\n";
}

Any thoughts?

Thanks in advance.
