The C code already exists in the perl core to do the current behaviour.
It would be nuts to re-implement this in pure Perl. More work, new bugs, not
quite compatible.
The sane approach is to add enough extra API to enable/disable the magic,
and let the same code do either.
This whole thread of threads is depressing me. A lot of talk. Little else.
