No.

You should be able to get the name using an alias:

void func(alias var)()
{
    writefln(var.stringof);
}

But you can't do it at runtime.

 Also how do I fix this:
 --
 functio(`i`); // Error: "i" is not an lvalue

You have to store the literal in a variable.

Can this be combined with the tuple parameter?

I needed it to get my function to accept
func( `name_i`, i, `name_ar`, ar, `name_b`, b ..etc..)
only the variables need to be ref.

I'll seconds this, there doesn't seem to be any way to generate tuples of 
aliases and this is another cases where it would be handy.
