I'm not finding a solution, this specific error is because a 
static array isn't an output range, see example below for "fix."

import std.range;
void main () {
     immutable(ubyte)  s0 = 5;
     ubyte[1] s1;
     auto slice = s1[];
     slice.put(s0);
}

But fixing this just results in not finding a match due to 
template constraints somewhere:

import std.base64;
ubyte[]  s0 = ['H','e','l','l','o'];
char[40] s1;
void main () {
     auto slice = s1[];
     Base64.encode (slice, s1);
}


base64.d(6): Error: template std.base64.Base64Impl!('+', 
'/').encode does not match any function template declaration.
