This is what I couldn't tolerate as well!!
I'm the same guy is looking for another new language, my path
is C/C++->Java->PHP->Perl.

I don't much care about this.

I'm the same frustrated as you about the Perl/Java and now Python,
Java is a good language, however it's not open language. Perl has some
language deficients as well. Python is so loose for type checking. However

today I just read the Perl6 vision, it makes me very exciting -

http://www.perl.org/perl6/pr/initial_meeting.html
The new Perl 6 will support Typing(e.g. "my Dog $spot") , OO, Threads and
more features!!

It also will bring some python's features into Perl.  :)
