GNU sed has the immensely useful --in-place switch:

sed -i -e x y

is roughly equivalent to

sed -e x y >y~ &&
mv y~ y

It would be convenient if bbe(1) had the same functionality.

It would also be very great if bbe could (optionally) perform block changes directly in source file, without creating temporary file first. At least for changes, which doesn't increase block's size.
