Is there a way to copy some text from a string? IE: Copy all A-Z,a-z chars from - $string = "Hello."

Joe Bloggs, John Cassidy, Abs,
It's pretty straightforward.
my $string = 'Hello, I must be going.';
# so we don't destroy the $string, we copy it.
my $azcopy = $string;
# I'll break this down, down below.
$azcopy =~ s/[^a-z]//gi;
print qq(\$azcopy="$azcopy"\n);
There is a single statement version, that I don't like the look of:
( $azcopy = $string ) =~ s/[^a-z]//gi;
For a more intuitive copy though this also kind of works:
my $azcopy = join( '', $string =~ /([a-z])/ig );
or this:
my $azcopy = join( '', split /[^a-z]/i, $string );
