module-define! MODULE NAME VALUE
e.g.
(let ((foo 'bar))
(module-define! (current-module) foo 5)
bar)
=> 5
Issue: this will be a top level binding, but a solution using `eval'
would also produce a top level binding (as it executes there to allow
lexical environments to be optimized...).
Doing such things, however, is fairly unschemey.
