You are right. Beside allowing nested functions (this is well known), it seems D2 also accepts the definition (with template constraint too) and instantiation of simple templates inside functions, I didn't know this.

But currently nested functions can't be overloaded. Probably for similar reasons inside a function you can't define more than one template with the same name. I presume this limit can be removed, so if you really need this you can ask for an enhancement request and if you can add a patch too to increase a bit the probability to see it fulfilled someday.
