syntax
(begin-on-demand #:export (fun-id ...) body ...+)
Defines each fun-id as a function that, when called,
dynamically loads and executes the body forms. The
body forms must contain definitions for each fun-id,
and the value of each fun-id must be a function.
A body form may be any module-level form except provide. In particular, require forms are allowed.
The body forms are placed within a submodule that extends the scope of the enclosing module (ie, module* with #f in the language position). Consequently, any references to sibling submodules must include a with ".." module path element.
