To correct myself: Since 0.42 or so there is way for externals to
override internals.
Personally I find it was wrong to implement this 'feature' without
providing a mechanism for a patch to protect it from using externals
that override internals. This really can make debugging hard and writing
portable patches impossible.

IIRC, there is even a documented case on the list, where someone posted
a patch, that was working only on some computers because a slight
difference between Pd's [wrap] and zexy's [wrap] and only on *some*
machines zexy was installed and did override Pd's internal [wrap].
