Read function from file, via `-F`?

If you look at the last example:
writing that query at the shell prompt, without paren completion/matching, is quickly going to become cumbersome/error prone.
What do you think of the idea to add the switch -F
(and something appropriate in long format e.g. --fn-from-file
), which would read a function from file?
Why would you want to write a function in a file?
Arguably, your $EDITOR has probably the best support for paren matching/completion. So that way you can write the function in a file and the pass it in as a command line option e.g.
cat foo.json | jet -i json -o json -F /tmp/fn.clj
Just an idea, what do you think?
Thanks
At this point you might just want to use babashka probably?
@dotemacs I know a better solution: -f
/ --func
accepts a file path as well. Just check if the expression happens to refer to an existing file, if not, execute it as a Clojure expression.

Oh, I love that! :)
Added it, just let me think of a nice way to test. PR coming up shortly.
