It can be "written" "better" by not giving closing parentheses their own
line.  It's a fairly accepted convention, so I'd suggest to warm up to
it. ;)

Also there are alternatives to updating the mode-line from a timer.
The mode-line supports a special :eval form with functions that are
called automatically, or you might update the values in
`after-change-functions'.

You never call anything interactively for its return value.  You should
pass the region points (region-beginning) and (region-end) as
parameters when (region-active-p), if that's what you want to do...
