Hrmm. What exactly is the value of the lambda in this scenario? The case for it seems aesthetic. Anyway, lambdas are not anonymous. They have a name but the author is not allowed to know it. So it seems like six of these or half a dozen of those.

I agree that in this particular case most compilers would be able to take advantage of the compile time constant even without any templates. But I also suspect there could be other cases where templates might be useful or necessary.
