I'm no perl monk but I'll offer this as another way to do it:

#!/usr/bin/perl

use strict;

# the original array elements
my @a = ('1', '2', '3', '4', '5', '6', '7');

# the element we want to remove
my $removeThis=3;

# container for array elements
my $arrayElement;

# Temporarily Store the elements we want to keep here
my @b;

foreach $arrayElement (@a) {
        
# it the element does not match the one we
# want to remove we add it to the @b array:

    if ($arrayElement ne $removeThis) {
        
        push(@b, $arrayElement)                        
        
    }

}

# replace the elements in the @a array with those in
# the @b array:
@a=@b;

# now print it out
foreach $arrayElement(@a) {print $arrayElement}

#result:
#124567

And I suppose if you want to turn it into a one liner this qualifies:

for $i(@a){if($i ne $m){push(@b,$i)}} @a=@b;

I honestly wouldn't know if there are any disadvantages to this approach. Perhaps others will comment on that.
