Answer 1

This is a limitation of the developer console, similar to what I described in What is the longest URI that Salesforce will accept through the REST API?

In short, the developer console is sending the code you have in your dev console's execute anonymous window to a REST endpoint as a query string parameter, and Salesforce can only handle URLs that are somewhere around 16k characters.

Your additional comments pushed you over that.

The use case you're describing sounds more like you should be adding the class into your org, rather than trying to execute it anonymously.
