There are already languages and tools that combine simplicity, sophistication and conceptual elagance. Scheme, Scratch, Oz, and yes, Hackety Hack.
There is a running joke in PL research that "programming languages = lambda calculus + constants". Scheme IS λ + k. JavaScript is that plus the kitchen sink with the Ringling Brothers Circus caravan in tow.
Scratch (http://scratch.mit.edu/) is getting a lot of attention from teachers in the UK. The government recently scrapped the existing IT curriculum in schools and wants more programming taught in schools.

OK, HNers, here is something to chew on...
You have around 5 million children in schools between 5 and 11 years old. You have professional and well trained teachers but with variable skill sets, remember teachers teach everything to a single class in that age group. You have decent numbers of PCs/Laptops and some tablet use. The government wants all children to learn programming. What are you going to do?
2. Hope that some of those students become teachers after their tertiary education where programming is included. Now you have 8 year olds being competently taught how to program.
3. Realise that teaching every kid to program doesn't work. The nerds now do hardware.
4. Government decides that all kids should learn to tinker with arduino.
My point is: not all kids needs to learn to program, only to know that it is something they might be interested in.
My point is: teaching environments like Scratch, or Web sites with visually appealing interactive content related to programming will be in demand. Watch the social stuff though, we have a big safeguarding agenda in the UK.

but you wont find anything specific in that (our dear government is good at saying what is wrong, and demanding change but less good at saying what it actually wants - you can't be wrong then!)
The links in my original post give the flavour. There was further consultation and a couple of speeches by Gove. I'll dig those out after tea
EDIT: one proposed curriculum model

This tells you where the ICT teachers are

(the emphasis on basic computer skills probably represents the managerial response to the previous National Curriculim: skills development was ghetto-ised into ICT instead of word processing as part of English, spreadsheets in Maths &c)
If you want to go lower-level better to learn some assembly (or at least C) instead...
Edit: Purity in the way that the crucial ideas are presented directly, and an intuitive understanding of primal computation can be gained directly.
