Yes but I'm not writing binary (or even C) code here. I'm using a high-level 
language that is supposed to hide the complexity of all that machinery and help 
me think at a higher level.

No issue about that.

I was naïvely thinking that inserting contents in a file is a frequent enough 
task (think xml nodes for ex), and actually even more frequent than appending, 
that there would be a relatively standard workflow proposed in the reference.

Stephan proposed that we consider inserting some extra info in the reference. 
When I'm done sorting my thing, I'll work on that.
