I think the existing documentation could be stronger without getting
into the details, however.

perldata now:

   ...The filehandle is left open pointing to the
   line after __DATA__.  It is the program's responsibility to
   C<close DATA> when it is done reading from it.

Perhaps that could be:

   ...The filehandle is left open pointing to the
   line after __DATA__.  The program should
   C<close DATA> when it is done reading from it.

Leaving it open leaks filehandles if the module is reloaded for any
reason, so it's a safer practice to close it.

I'm not sure if we need to explain why since reloading is pretty rare,
but we could with a single sentence like that if we chose to.
