Yes, I've been playing along that generalization effort as I did not see it
compromising the interface or muddling the intent. For me the clarity was
the goal, the generalization was a bonus. I do not feel
int i = convert<int>::from(string)
has been generalized at the expense of clarity. Quite the opposite. To me
above does exactly what it says... in the best possible (IMHO) way. I do not
believe that something clearer like "from_string" will better reflect its
purpose as the "string" is open for interpretation and the above converts
from various string-like *containers* (like vector<char>, list<wchar_t>).
Same goes for 'to_string' as I need to convert to char and wchar_t-based
strings and most likely need to convert to u8char strings. Therefore, I do
looks/reads better than

Yes, I indeed have that feeling that the generalization option will never be
exercised. However, to me the generalization has been accidental, a bonus.
The main goal of the exercise (for me) has been clearing up the interface to
say what it does.
