No Library is perfect, but the "I which I had" list for the STL is much
larger then for container out of IBM's OCL. The OCL was not designed for
academic correctness bit but for usability.

In 99.99% of all cases I don't need strings on user defined types. I need
base_string<char>. I can see that I one day might need
base_string<wchar_t>, but I have not until now. They made all that funky
design which I just never need. And for that:
int
string::asInt();
throw (bad_value);
and
explicit
string::string (int value)
throw();
are missing. Two functions I am missing on daily basis. Sure, I am an
experienced programmer, I can do that myself - but a proper library should
have all the function one need on a daily basis.
And they could have had both:
class string:
public: base_string<char>
{
public:
int
string::asInt()
throw (bad_value);
explicit
string (int value)
throw();
}
Would have been so easy, so usefull but it would not have been a template.
The "all is template" religion got in there way.
And just for the record: atio is a C function - you need the overhead of
convertion the std::string into a char* and std::strstream seem quite heavy
weight for just a simple task of convertion a string from and to an int.

Martin
