 This subproject implements the following features:
 
 - Expression Language and its parser.
-- MST as expression language's syntax intermediate representation.
-- Type-safe builder of MST.
+- MST (Mathematical Syntax Tree) as expression language's syntax intermediate representation.

 - Evaluating expressions by traversing MST.

 `kmath-ast` JVM module supports runtime code generation to eliminate overhead of tree traversal. Code generator builds 
 a special implementation of `Expression<T>` with implemented `invoke` function.
