I actually really like the Base64Impl.  It allows you to build DecodeMap
statically, and provides a very nice api for using custom base64 variations.
I'm not sure how you'd do anything this nice with runtime parameters.

alias Base64('^', '&', Base64.NoPadding) CustomBase64;
CustomBase64.encode(data)
CustomBase64.decode(encodeddata)

vs

encode(data, '^', '&', Base64.NoPadding);
decode(encodeddata, '^', '&', Base64.NoPadding);

I didn't really see this until I started using it. :)
