Re^2: zlib error

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 %...
