Hi Eric,

just a question: It is possible to pass array objects with external linkage
as template parameters, is there any way one can manipulate them at compile
time? I am wondering, if one can pass begin and end iterator as template
parameters and verify such a string. That might have real impact on compile
time...

If I can use such a function:
tempalte<size_t N>
void array_len(char (&arr)[])
{}

I might be able to pass instantiated function template function to the
template to calculate the string length and than I have begin and length of
the string, and can apply recusion at compile time. What do you think about
it?

With Kind Regards,
Ovanes
