Finally I have managed to translate a 2400 lines Python Code to a nearly 2700 lines Nim code. The hardest part was a 550 lines long Python generator which calls itself (recursively) in many places and is called itself by another generator. This was only possible with the brilliant iterate macro by Timothee Cour. Unfortunately this had a bug when called recursively. Only with the fantastic help (sometime within seconds) of very kind people on Gitter, I managed to apply a non-trivial fix to that macro -- see https://github.com/timotheecour/Nim/issues/378

I've learnt a lot about macros and I'm still learning.

My personal conclusion is as follows:

Nim is a very powerful language - but much more difficult than it looked at first glance. For me, Nim is a blend of the meanstream languages C++ and Python. It is much easier and safer to use than C++. In many respects it is as comfortable as Python - which is a surprise for a strictly typed language. But it is much more performant than Python.

Nim generates fast native code - and is nearly self-contained, e.g. it needs only very few system libraries

It can profit from (true) multi-threading

Its Generics are much easier and consistent than C++. Its macro language is nearly as powerfull as that of Lisp ... but it still has a steep learning curve ( with all its pragmas ). I like the brilliant quote do: feature - I'm only missing some quoting mechanism to replace the boilerplate
```
 let X_id = ident"X"   .... quote do: ..... `X_id`  
```

I am convinced Nim can replace Java sometime in the future if the community grows further, some big players jump on the bandwagon such that it gets on par with Javas wealth of libraries.

I predict a bright future in the growing market of embedded systems and I can image a mobile phone with a Linux kernel but infrastructure based on Nim.

Many thanks to the creator and the contributors to the Nim language!
