I can see now (side note to myself: do not ever never again reply to
emails before going to sleep at morning, sorry).
So, can this problem be described as that OP cannot expand this stuff
in his memory (this jello ram between the ears), because it has got
too complicated? Perhaps this can be helped by writing things into a
proper script? I performed a lot of $() things in cli but never
learned about M-C-e, so I assume I never did things that required this
trick. Hence a script suggestion.
Another trick may be executing the line with echo prepended - should
do all expansions and write what will be executed. I think it is not
going to work too well if for loop is being echoed, and other such
things, so perhaps quoting a command and echoing would do the job.
Seems like it works in bash as I hoped:
==>$ echo "for i in $(seq 3); do circle ${i}; done"
for i in 1
2
3; do circle ; done
