I have a piece of code that gathers a set of substrings of fixed length from a longer string, thus: 

my $i = 0;
my $size = 10;

while (my $substring = substr($string, $i, $size)) {
    
    push (@substrings, $substring);
    $i += $size

}

This works fine, except that if the size of the segment does not evenly divide the size of the string, getting the last segment results in a warning message: "substr outside of string"

While this doesn't hurt anything, it offends my sense of order to see warnings like this where everything is working correctly :-) I could rewrite the code to use a for loop after working out the number of substrings based on the length of the string and the size of the substring, but I find this rather awkward and inelegant

Any suggestions for an elegant solution to this problem that avoids the error messages?
