Thanks, But this example works:
void main()
{
T input(T)()
{}
}
Why ?
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.

The spec explicitly says:
"Unlike module level declarations, declarations within function scope
are processed in order. This means that two nested functions cannot
mutually call each other:

Future directions: This restriction may be removed."
My guess is that it will become possible eventually.
