Actually, what most people expect is for Perl to read their minds
Well. A Real Gift. Actually, what Perl expects from most people is reading the minds of its developers.
Wow. This has been blunt. I don't mean it that way...
Going from low-level Perl (a.k.a Baby-Perl) to Sindarin Perl is a steady learning curve, along which one experiences many pitfalls, reasonable and questionable defaults, and really weird but useful things, and it is most helpful to get acquainted with Perl's history to understand why things in Perl are as they are. Practice sharpens the understanding, there's always something new to explore and find, at every corner are the thoughts, not only of you, but many, forged into code, at times long forgotten. Understanding Perl is in great part understanding its history, its whences and whys: it is reading the mind of its developers, and much wisdom can come thereof.
Going from Perl 5 to Perl 6 is like moving from Sindarin to Quenya. In the Sindarin world, that's the high-level language spoken by those who have been in the blessed realm of Valinor, and came back to Middle-Earth.
But we Grey-Elves haven't been there, and we are not Baby-Perl-Speakers any more. We know Valinor's lore by third hand, from Tales of Apocalypses and Synopses, and so we will have to read your minds to somehow keep our language fluent and our expressions unambiguous, and mixing Sindarin with Quenya will lead to trouble... that seems to be the biggest obstacle for transition.
The Grey-Elves did choose not to leave the lands where they awoke and saw the stars..
