Ted everything after the first __DATA__ or __END__ is just data, even
another __DATA__ or __END__

Just try this code:
----------------------
print while (<DATA>)
__DATA__
a
__END__
b
---------------------
you will see that everything after __DATA__ will be printed.

There are differences between __DATA__ and __END__ regarding package/
modul scope but this has no effect on highlighting or cperl.

And yes, moduls like  SelfLoader can be used to eval code in the DATA-
Section on demand, but IMHO SelfLoader is an edge case NOT the rule.

Anyway my preferred solution would be a syntax possibility or local
cperl-variable to decide if the DATA-Section should be highlighted as
perl code or not.

maybe something like

----------------------
package FOOBAR;
use SelfLoader;

__DATA__   #perl-code
sub bla {
   ...
}
---------------------
