things that look different

[Michael Stillwell]

On the topic of things that look different but do (almost?) the same 
thing, is there ever any reason to prefer one of these over the other:

my $v1 = do {
   1;
};

my $v2 = sub {
   1;
}->();

?

(The sub approach lets you do an actual return, which does suit the 
construction, but the "}->();" bit sure is ugly...)
