Here, yes, but I always used an alias written so long ago (for
ISO-8859-1..UTF-8) that I hadn't ever thought about using it
for base64. (My alias's name is a reminder that it overwrites
whenever filenames are given.)

I'd be surprised if people ran the above without first cutting/pasting
and line-editing it to something like:

 $ recode b64..data <<EOF | gunzip | hexdump -C
   H4sIACv1FmQAAzXMPQrCQBAG0H5O8TFEMII/BA3BVF7AXoLFsI5kCdl1d5JC8PCSIuVrnro+gm82
   QPBVO4aINKtNPoYrU1Z5YZ+RyIkpuNh+sg/TG7wxRpHwg/VSXWqbx5LhA6E7Vee6EafPXQld9ofa
   oW0Jq+9xoZo4+gNQ3NCSfgAAAA==
   EOF

(very simply done when using bracketed paste, of course).

Cheers,
David.
