Redis feature request - CLI: access value from prev reply

not sure if there is already a way to do this, but it would be great to be able to reference values from the previous reply, something like this maybe:

redis> keys *like*
1) "user:4ea1e4575c0e23ad42000012:likes"
2) "likes:4ea1eac2b466d57a45000044"
redis> smembers $2
...
