In the version of ZWEI on system 29.95 NWS, with microcode 669, on LISP Machine One:

It would be useful to have a (single-key!) command that would
take the S-expression after ., kill it, evaluate it, and put
its value back into the buffer where the s-exp was.

This can be done by killing it, running Evaluate Into Buffer, un-killing,
Return, but that takes more keystrokes, and also is slower when iterated
by a keyboard macro, because it insists on printing prompts in the echo area.

One thing this lets you do easily is clever keyboard macros that for
example find certain numbers in the buffer and increment them, etc.
