"A gentle introduction to Symta" - Nikita Sadkov

"Advanced Symta" - Nikita Sadkov

Where are these books?!

Nikita, write and publish!

Fun fact: official Russian translation of the Gentle Introduction to Haskell is called «Мягкое введение в хаскелл», which has VERY clear sexual connotations (literally: soft insertion into Haskell)
