I see, even the italian language is a romanic language, there are some pitfalls when translating from/to German.
As a German it feels natural to read some documentation or code in German (I guess it's the same as an Italian?) but especially with technical topics and terms I tend to go with english because often there is no good transaltion for english terms regarding technologies and is clearer to use the english word. Also to prevent misunderstandings. So for learning another language it could be beneficial, but to build a common understanding of things, english is preferred.
Just as you stated in your post, it is very important to point out even the slightest mistakes :)
