Also they would tend to fill up the symbol table with junk.
If an error is really an error, it's not fixable from within the patch
anyway. An object that encounters a showstopper error can call
pd_error() instead of post() to print to the console, The user can
then "find last error' and the object will be highlighted. Then they
can plug the cable back in or whatever.
