Perl copy vs system cp

What are the pros & cons, if any, between using Perl's copy module vs OS's system cp, for copying a file to another directory? Or are they exactly the same?

1) Perl's File::Copy module, as in
Code:
  
copy ($filename, $dest_path) or die "ERROR: Cannot copy\n";

2)
Code:
if (system ("cp $filename, $dest_path") != 0) {
  <do something>;
} else {
  print "ERROR: Cannot copy\n";
}

PS. Sorry if this is already discussed in other/older threads.

Thanks.

PPI::Document::File(3)					User Contributed Perl Documentation				    PPI::Document::File(3)

NAME
PPI::Document::File - A Perl Document located in a specific file DESCRIPTION
WARNING: This class is experimental, and may change without notice PPI::Document::File provides a PPI::Document subclass that represents a Perl document stored in a specific named file. METHODS
new my $file = PPI::Document::File->new( 'Module.pm' ); The "new" constructor works the same as for the regular one, except that the only params allowed is a file name. You cannot create an "anonymous" PPI::Document::File object, not can you create an empty one. Returns a new PPI::Document::File object, or "undef" on error. filename The "filename" accessor returns the name of the file in which the document is stored. save # Save to the file we were loaded from $file->save; # Save a copy to somewhere else $file->save( 'Module2.pm' ); The "save" method works similarly to the one in the parent PPI::Document class, saving a copy of the document to a file. The difference with this subclass is that if "save" is not passed any filename, it will save it back to the file it was loaded from. Note: When saving to a different file, it is considered to be saving a copy and so the value returned by the "filename" accessor will stay the same, and not change to the new filename. TO DO
- May need to overload some methods to forcefully prevent Document objects becoming children of another Node. SUPPORT
