The complex value is basically a simplified envelope for script
functionality for a simple case of a single string with (optional)
In most cases (unless you are targeting your code for old nginx
versions) a complex value will be ok for you. Note complex values
were introduced relatively recently, so in many cases nginx code
still uses script directly.
There are also some specific situations though, when you may need
to use script functionality directly. E.g. proxy module will do
this when evaluating proxy_set_header directives, as this allows
flush uncacheable variables only once.
