Hi, I have another question about that do{} construct. Is there any reason to use a do construct and not:

bless \my $anon, $class;

or the even easier to type:

bless {}, $class;

    The first bless \my $anon, $class; retains the name $anon for the rest of the code block - it is no longer anonymous.

    The second bless {}, $class; constructs an anonymous hash, which I believe uses more memory. I cannot claim I invented the use of the do{ } construct in this way, I stole it from TheDamian.
