Alan notes that: The basic idea was to extend the parser token stack

postprocessed to record the type of each entry on the stack as it was
created, and the parser patched so that it could unroll the stack
properly on error.

+When faced with a BSD vs. SysV -style interface to some library or
system function, perl's roots show in that it typically prefers the BSD
interface (but falls back to the SysV one). One example is getpgrp().
Other examples include C<memcpy> vs. C<bcopy>. There are others, mostly in
