Yes, I have to agree as I've been feeling the same. I read/write a lot of
configuration data and I have to rely on XML for communications. I need/use
string-to/from-type conversions a LOT in the lexical_cast manner. I've never
had the urge of integrating type-to-type conversions into any kind of a
framework as those conversions seem so type-specific that the following
always felt as the natural choice:
That said, I was not sure if my experience was that exemplary so I did not
want to shut the door for such a possibility. I am still hoping that that
fairly neutral interface
int i = convert<int>::from(str);
does not sacrifice the string-based origins of that whole discussion and at
the same time leaves the door open whatever might come our way... if ever.
