 I tried to find optimal (== most readable) implementation in every framework, but comments are welcomed! There are lot of comments in the code explaining why I chose such implementation and some FIXMEs on places which I do not like, but which cannot be implemented differently or which I have troubles to improve...
 
 Furthermore, I considered (and tried to implement) even following frameworks, but it turned out they do not meet the conditions:
