I agree that it will be interesting to have a way to make this bar
transformation using a class template unary
int main()
{
     int A[5];
     A | boost::adaptors::transformed(unary<foo>());
}
Not possible.  There's no way to preserve
default arguments when taking a pointer
to a function.
Yes I know.

Could a lambda help on this context?

int main()
{
     int A[5];
     A | boost::adaptors::transformed([](int a){ return foo(a);});
}
