Curious. This addresses a question that I recently had.

I thought that `printenv` showed a list of all known variables and their 
values, but I recently realized that it was missing a lot of them.


Q » Is `typeset` what I should use for that? Or is there a better way?


For example, I have sometimes used `printenv > all-vars.txt` to get a 
'snapshot' of current variables. Seems like `typeset > all-vars.txt` is 
much better. I just compared them and `typeset` shows 291 vs `printenv` 
showing 110.
