-Some muppet just brainfarted a long list of personal dislikes about Perl.. I've tried to make sure this remains objective, I could dig up an even longer list along the same lines for any of Ruby, Python and especially PHP-Aaron
+I think everyone agrees that Perl5 is difficult for large, maintainable applications, and no one wants to advocate continuing to use it. But still, there's some red herrings:
+* Certain syntax things are confusing for new users
+** Granted. But it seems that there would be a strong expectation that anyone programming in a particular language would be far beyond the "new user" stage before they attempted anything big/maintainable/etc -- regardless of the language being used.
+* Perl doesn't check the type of arguments to subroutines.
+** Given that it's a typeless language, what is there to check?
+* <tt>$$foo[1]</tt> and <tt>$foo->[1]</tt> mean the same thing.
+** This is analogous to a C/C++ construct where <tt>ix->member</tt> and <tt>(*ix).member</tt> mean the same thing.
+* You can't make subroutines private in a class.
+** Not true:
+ package Foo;
+ my $private_method_ref =
+     sub {
+          print "hello, I'm a private method\n";
+          print "There is no way to call me outside of this package\n";
+     };
+ sub public_method
+ {
+   # call private method
+   $private_method_ref->();
+ }
