PPL - the latest version 2.0.7 is available

I’ve been working on the project PPL for almost 3 years.
During this time, many errors were eliminated, support for many libraries (general purpose - Array, File, String, etc…
and special - DataFrame, Statistics, Excel)
and a large number of examples was added, documentation was improved. Since the project is available on GitHub, I see that programmers have begun to become interested in the PPL language.
The last significant addition to the project is support for structures within structures, creation, replacement and execution of functions within structures, which implements the object-oriented programming approach.
I highly value the opinion of experts in the field of programming language development and will be glad to receive critical comments on the PPL language.
