2) This is about the reduce templates. As I've commented, I
can't use a template lambda with reduce, but I can use a

"template instance reduce!((a, b) => a + b) cannot use local
'__lambda1' as parameter to non-global template reduce(alias
fun)()"
No idea for this.
The use of the global identity template will fix this:
