That's an okay approach if the only time an expression produces a result variable dwim-print should not delete is when a persistent variable is explicitly mentioned.  But anyway, since that's the case we're fixing, and checking as a persistent variable as a short-cut early on isn't a bad idea, it is fine for these purposes.

I think you need to get the persistent variables for whatever the language of the expression happens to be, not just get all the persistent variables. Otherwise, if you define a C persistent variable, then stop in a swift frame and do:

(lldb) p $works_in_c
10
(lldb) p $works_in_c + 10
unknown identifier "$works_in_c"

which would be confusing.
