I fully understand your point and appreciate it, but I have to disagree. I admit that there are a couple of things that are still obscure to me among those that I have studied, but it is really very few.

One of the reasons for such difficulties is that the documentation available is still insufficient. The official documentation is rather good (although still a bit incomplete), but sometimes it is a bit terse and you (or I) would need some further explanations, such as what you would find in the Llama and the Camel book for Perl 5, not to speak of the numerous tutorials available for Perl 5. As an example, really understanding Perl 5 references and associated data structures took me some time, but the available articles helped a lot, understanding it from just the official Perl documentation might have been more difficult.

As a relatively early adopter of Perl 6, I know that it is a bit more complicated for me than it was twelve or thirteen years ago when I picked up Perl 5, because the documentation is much less abundant, but that's OK, I expected that, and I am spending quite a bit of free time trying to help produce better documentation for Perl 6 (well, mostly in French so far, but some in English to come out soon).

But, really, Perl 6 is implementing the DWIM principle just as Perl 5, it is not difficult, you just have to pass the barrier of the (relatively few) differences between the two versions of the language. It does take a bit of efforts, but no big deal, really.
