### 7`` Parsing for Bodies

(require syntax/for-body)

The syntax/for-body module provides a helper function for for-like syntactic forms that wrap the body of the form while expanding to another for-like form, and the wrapper should apply only after the last #:break or #:final clause in the body.

> procedure (split-for-body stx body-stxes) → syntax?
> stx : syntax?
> body-stxes : syntax?

The body-stxes argument must have the form (pre-body ... post-body ...), and it is rewritten into ((pre-body ...) (post-body ...)) such that (post-body ...) is as large as possible without containing a #:break or #:final clause.

The stx argument is used only for reporting syntax errors.
