To elaborate further on what davido and grandfather have said -- you can make it nicely terse using the syntax "while (my $a = shift @a)", as in: 
#!/usr/bin/perl -w

# Strict
use strict;
use warnings;

# Main program
my @a = (1..5);
while (my $a = shift @a) {
    print "Deleted value: $a\n";
}

Now that you are checking for the changing condition (the individually shifted-off element), you will get what you expect.  If you're not going to use any of the values from the array, then as EvanCarroll pointed out, the easier/quicker way to delete all of @a would be: 
@a = ( );
