I have two issues with respect to the merging of DELETE-FILE and

1. For physical pathnames it seems straightforward, but I do
wonder if there are any unexpected gotchas when using logical

2. DELETE-FILE is defined by the CLHS. People who use ECL without
reading too much of the CLHS may expect DELETE-FILE to behave
similarly across implementations. For example, it was a huge shock to
me that in CLISP, PROBE-FILE signals an error when called with a
pathname that represents a directory.

This is one area where a CDR would be beneficial to the community to
try and address some of these inconsistencies.
