-0  When taking a binary file and attaching it to the text of a mail
message using BASE64, the tendency to say you're "encoding the file in
BASE64" is very strong.  I just don't see how such usages can be
avoided in discussion, which makes the types of decode and encode hard
to remember, and easy to mistake in some contexts.

+1  The coding conversion operation has always felt like a constructor
to me, and in this particular usage that's exactly what it is.  I
prefer the nomenclature to reflect that.
