Allow private main
The .net compiler for real stuff doesn’t require the class
Main() is in to be public nor
Main() itself to be public. In fact, there’s no reason to write any access specifier in code since it doesn’t need to be public and is just extra noise, so I normally don’t in my one-off programs. Even [the VS templates for simple console apps](https://gist.github.com/binki/1f8ed17ed87cf4e78d3771d6f77cd0f9) uses
private (by allowing the default access by omitting the keyword).
Because .net fiddle doesn’t support this, it is impossible to copy/paste simple programs from VS into it to share with others with all the output, etc.
Please make the fiddle support private
Main() to make writing and sharing fiddles less work.
