FWIW, my impression was that the point is to duplicate many of the editing features and data structure manipulations (currently bound to Lisp) in Perl. What with different GC strategies and general philosophy (Lisp usually works on copies; Perl does in place transformations, etc) data safety strikes me as involving lots of details which could be different from function to function in the Perl embedding. John has paid attention to GC, though; maybe it's not as big a deal as I'm making out. It's most worrying to me if a Lisp programmer calls a perl module, perhaps implicitly.
