[ID 20010425.007] hash key; pseudohashes
Message ID:

This is a bug report for perl from hans@kolej.mff.cuni.cz,
generated with the help of perlbug 1.28 running under perl v5.6.0.

	Dear perl team,

   I have two things. In a perl version 5.? was a deccision to understand
bareword in hash key ($hash{bareword}) as a string. I geeted this.  But
while not to do the same if using hash like array -- if there are a list of
keys, e.g.

	$STAT{dev} = 1;		# thats OK

	# dots means shortcuting here and has nothing with perl
	@STAT{dev, ino, mode, nlink,...} = (1, 2, 3, 4,...);

   These could be strings from barewords in the same way
as "dev" on the first line is.

   My second problem is similar. I also want to assign to more hash entries
as to an array. But to pseudohash, e.g.

	@st{uid, gid} = (500, 500); # OK, clasical hash, but should write ""
	$stat = [\%STAT];	# pseudo-hash
	$stat->{uid, gid} = (500, 500);		# line 8

  Results:
	:! perl-5.005 /home/hans/Perl/stat.pl
	No such array field at /home/hans/Perl/stat.pl line 8.

	:! perl-5.6 /home/hans/Perl/stat.pl
	No such pseudo-hash field "uidgid" at /home/hans/Perl/stat.pl line 8.

  The error message from perl-5.6 I consider as bug. Why concatenating the keys?!

  Results are same as if I give "" around uid, gid or the keys are already initialised
or if I use the array on the right side of assigning.

  I use perl 5.005_03 from Potato and perl-5.6 from Woody on Debian Linux.


	Best regards,

						Hans
