##### 14.8.2.8 `:no-expand`

By default, code blocks are expanded with `org-babel-expand-src-block` during tangling. This has the effect of assigning values to variables specified with `:var` (see var), and of replacing “noweb” references (see Noweb reference syntax) with their targets. The `:no-expand` header argument can be used to turn off this behavior.
