Dear Arthur and Vladimir Nesterovsky,

I sincerely apologize for modifying and distributing the source code of
your yield return implementation without asking for your permission.
Although it happened unknowingly, it was a shameful thing to do.

Between late 2010 and early 2011 a friend of mine showed me some source files
of a yield return annotation handler. He explained the basic concept to me and
asked if I could, based on these files, add a basic yield implementation to my
lombok fork (now lombok-pg).
Please note that the files he gave me didn't contain any readme, license,
copyright-header or package name that could point me to your blog and therefore
to your implementation. That's why I assumed he wrote it himself.
Up until now I just maintained the buggy and incomplete yield implementation seen
in lombok-pg based on the files he gave me.

Although it is probably to late, I hereby ask for your permission to
modify and distribute the source code of your yield return implementation.
I will credit you for your work in the corresponding source files and the
feature documentation by stating that the yield implementation seen in lombok-pg
is largely based on your work.

I hope you can forgive me. I look forward to your response.

Kind regards,

Philipp Eichhorn
(author of lombok-pg)

Hello, Philipp!

1. We do permit the use of our idea, algorithms, sources.
2. We suggest to use our sources as the base, as they are better tested, and support closable yield iterators. They are important when your iterator uses resources that should be freed in finally clause.

Thanks.

Hello Vladimir,

I will gladly follow you suggestion.
Thank you.
