Yes. You are right. But I wanted the way to store my queries in any major database. And I wanted natural simple queries.

If I need to check my dictionary I want to use something similar to natural language.

lambdas and filters are greate, but not obvious at a glance.

If I want to check my dict: "Username is 'john' and age is greater than 23"

I will make this query: "`username` == 'john' and `age` > 23"

This query is obvious (i hope it is) for anyone from first glance
