Dear Otared,

You are welcome. It is not my code.
As you know I am just an enduser of ConTeXt.
I also always thank to Hans, ConTeXt team and this list.
Here are always answers!

I mainly use ConTeXt to prepare documents, math papers, and class materials.
It is really good to use Metafun and Lua inside ConTeXt with ease. 
And the animation feature is really good to give better presentation to students.

As you said \dostepwiserecurse would be useful in many ways.

Please share your ideas too.

Best regards,

Dalyoung
