| First, I don't know if I've misunderstood what you meant by "show how
| it was written,"

If user writes vector<int>, I would like to print vector<T> [with T = int],
not vector<int>, <default> > (or variants).  Similarly, if user
wirtes vector<int, allocator<int> >, then ideally I would also like to
print vector<T, Allocator> [with T = int, Allocator = alloctor<int>].

There are discussions about carret diagnostics, but this is not it.

I can't ignore ignore the rest, not because I'm goiing to do something
stupid but because you also request to tke what you're saying
"seriously".  And also, because, I'm a bit fed up of your arrogance.

| This is very disappointing.  Condescencion is entirely uncalled for.

oh really?  when people try to do things, you immediately think or
"fear" that they are going to do the wrong thing.  Oh yeah, that is
not called "condescencion", you're just feeling they are stupid.

| I won't claim to know what your level of expertise is, but I know I've

| take what I say seriously.

Oh, I do read what you write -- everytime I have the chance.  
I know also from experience usually it is probably good not to say
anything contrary to your opinions.  But I can't resist, especially
when you don't quite understand the variations.
