Re: zlib error

The short answer to your issue is that 'Compress::Zlib::' is a string and not a hash reference, so perl fails when it tries to dereference the string (%$package). At first I thought you were saying that the posted code was from Compress::Zlib, but I find no such code, so I'll assume that is code in a local module. What are you trying to do by defining $package? Are you the original author of Gzip.pm? This looks a lot like using symbolic references to muck about in the package symbol table, which is not allowed under strict 'refs'.

so perl fails when it tries to dereference the string Interestingly, the code `my $package = "Compress::Zlib::"; print "$package defined\n" if defined %$package;` [download] works fine with 5.8.8 (with strictures enabled), while 5.10.1 complains as shown in the OP... Update: and with 5.12.0 you get `defined(%hash) is deprecated at ./835534.pl line 10. (Maybe you should just omit the defined()?)` [download] ~~...which also does work fine (with strictures) when you do so, i.e. when you write `... if %$package;`~~ nonsense (I had forgotten to comment out the `no strict 'refs'`, which I had added in the meantime...) — in other words, for both 5.10 and 5.12 (but not 5.8) you do need the `no strict 'refs'`, even without the deprecated `defined %...`	[reply] [d/l] [select]

which also does work fine (with strictures) Not for me. `$ perl -v This is perl 5, version 12, subversion 0 (v5.12.0) built for i686-linu +x [snip] $ perl -Mstrict -wle'my $pkg="Foo::"; print(defined(%$pkg)?1:0)' defined(%hash) is deprecated at -e line 1.

Can't use string ("Foo::") as a HASH ref while "strict refs" in use at + -e line 1.` [download] Update: Oops, seems you noticed your mistake while I was posting.	[reply] [d/l]
