Wth is wrong with:

data=3D$( sed -e '...' somefile ) &&
        echo "$data" > somefile

or

set -e
data=3D...
echo "$data" > ...

or

exec 3<<EOF
$( ... )
EOF
cat > ... <&3

or

(I digress)

Infinite variations, but the gist is that sponge looks to be trying to help s=
h(1)/similar when help is unneeded.

Why buffer data into memory via fork-exec-pipe to sponge when you can buffer=
 to native namespace without pipe to sponge?

Am I missing something? Why do we need sponge(1)?
