Ahem, IOStreams are a flexible formatting and parsing framework that uses
a plugin mechanism for the actual work. This is _by far_ not functionally
equivalent to C stdio, so you are comparing apples to oranges. Further,

It's flexible - for sure. But why do I have to pay for all that
flexibility ?

You don't, just use something else. You could e.g. format the data with
dedicated functions and still use e.g. std::filebuf for writing.

I think it's overkill for most of the daily tasks a C++ programmer has
to do.

I regularly need to write different Unicode encodings or codepages. I
regularly redirect streams by changing their target streambuffer. I
regularly need to change the output format to the C locale for file IO
while I still need the local culture's output format for user IO. I
generally don't care much for formatting performance because IO throughput
is much (s)lower anyway.

Andre, I understand your point and I particularly agree that formatting with
iostreams tends to become unreadable (hence Boost.Format and similar
things). I don't think it's the only side though.

Greetings!
