First, I think the "as usual" is a bit unfair. ;-)
Second, if you use undocumented stuff, keep in mind that they may change
without prior notice.
Third, you may want to look at `boot-9.scm' for examples of binder
procedures. Basically, each module can define a binder procedure (using
`set-module-binder!' or as an argument to `module-constructor') that is
called whenever a symbol lookup is not satisfied by the module's symbol
table (its "obarray"). When invoked, that binder is passed three
arguments: the module, the symbol being looked up, and a boolean
indicating whether that symbol is to be defined or just looked up. See,
for instance, `make-autoload-interface' (in 1.8) for an example (or
Andy's link).
Hope this helps,
Ludovic.
PS: FWIW, I'm also not convinced that this is the right approach to
implementing shell-like constructs in Guile.
