Perl's pseudo-objects are, in my opinion, one of the weakest aspects of Perl. So I'm not going to disagree with you that many other languages do that one thing better. But it's not always appropriate to nest your objects that deeply anyway (in any language, that can quickly become a mess).
In my personal opinion, I prefer C-style braces over whitespace formatted blocks. Which means I find reading function and iteration blocks much easier to read in Perl than I do in Python. I'm not saying one is "better" than the other, but just offering a counter argument for how subjective language aesthetics really is.
Just to counter your points, having done many years of Perl, and now a Python.
Perls OOP does feel like a bit of a hack. But it does make it transparent how everything works. I learned Java at University, and everything OOP was a black box and I had no real understanding of how it worked. After learning the Perl way, its really obvious what is going on because it is so transparent. Your current object doesn't have a method? Just look along the @ISA array until you find an object that does have it.
Pythons whitespace is a pain at first, but having used it for a few years, one problem I do not miss is loosing a brace, when reorganizing blocks of code. You cut a few lines of code and paste it somewhere above or below, and your IDE shows you you are missing a brace somewhere. The indentation looks fine, so you can't see where it is.
The whitespace thing is worth it to get rid of that problem alone.
Aren't there just as many problems with cutting and pasting python and getting either slightly off indentation or mixed spaces/tabs? If the IDE fixes the problem, I don't see why it's any different for braces as it is for whitespace. There's easy ways to identify both.
Arguing that one is better than the other is like arguing over which colour the best. Which is why I get so utterly sick of Perl being compared with Python - they are all going to have their strengths and weaknesses so at the end of the day, the "better" language / syntax boils down to personal preference.
I wasn't arguing that either way was better, just seeing the positives where negatives have been noted.
I personally haven't wasted anywhere near as much time with Python indentation compared to missing braces. I hated the whitespace thing at first, and it was only after going back to doing some Perl I noticed that the problem wasn't present in Python.
Though the fact that most other languages use braces is a pain, as it makes swapping between Python and Java / Perl / JavaScript / etc tricky, as I tend to get into the habit of using or not using semicolons at the end of a line.
In my personal opinion, I prefer C-style braces over whitespace formatted blocks. Which means I find reading function and iteration blocks much easier to read in Perl than I do in Python.
