Just thinking aloud (JTA?), there's a little verbosity gap in the
docs at times. For example, compare 'mkdir' and 'unlink docs:
mkdir Creates the directory specified by FILENAME, with
permissions
specified by MASK (as modified by "umask"). If it succeeds it
returns true, otherwise it returns false and sets $! (errno).
etc...
unlink Deletes a list of files. Returns the number of files
successfully deleted. etc...
JTA again, why not add "or returns false and sets $! (errno)." to the
sentence above.
Surely any perlfunc doc bloat would be trumped by the added clarity.
