Here's the "standard" way of doing that:
"save user's current statusline option
let g:CF_statusline=&statusline
"set statusline back to previous setting
let &statusline=g:CF_statusline
Further, if there is no need to access CF_statusline outside the
script in which 'statusline' is saved and restored, a script
variable is often used instead of a global variable to avoid
polluting the global name space. So you might consider using
s:CF_statusline instead of g:CF_statusline.
