Yes, but...

Personally, I remember people using the C++-like syntax...
my $obj = new Foo::Bar;
...on this list and being told to use the alternative syntax...
my $obj = Foo::Bar->new;
...instead. It seems better to just avoid the name "new" entirely so
it isn't confused with other languages. I think it will be less
confusing for people that way. I know that I found it confusing to see
the C++-like syntax, only to have people on this list discourage it
and say that it doesn't do what we think it does. I'm not fixed on
'create', but generally I name my "constructor" functions in C
"${struct_name}_create" (where $struct_name is the name of the
struct), so it just seems logical that I would name my constructors in
Perl 'create' as well (after all, that's essentially what they're
doing).
