Re^3: What are all the Perl data types?

Otherwise any blessed scalar is another type?

I tend to think that a scalar has a reference to a blessed thing rather than the scalar itself being blessed.

my $unblessed = {};
my $blessed = $unblessed;
bless $blessed, 'Holy::Holy';
printf "%s\n%s\n", ref $unblessed, ref $blessed;
__END__
Holy::Holy
Holy::Holy

That's just a nitpick, though.

I ordinarily wouldn't think of some user-created object as being a separate data type except that they can be overloaded to act just like one. Where does something like Math::BigInt fit in? I think this is a point on which reasonable people can disagree.

That also makes me wonder if we could count iterators somehow.

I don't know what you mean by this.

Just a nitpick back: "sv_bless(SV* sv, HV* stash);" (perlguts); it really is the scalar that's blessed, rather than the other way around. I think this is a point on which reasonable people can disagree. I just recently read a discussion on (usenet or a mailinglist) about how the discussion of dynamically vs statically typed doesn't really make any sense unless you agree on the parameters before hand. I suspect this is sorta the same thing. -Paul	[reply]
