[plt-scheme] eval and modules

> Compiling an 'eval'-intensive Scheme code to standalone executable

That's a problem. The way that the module system simplifies various
tasks (like compilation and creating standalone executables) is to
avoid the top level.

I don't have a good answer. When I write code that uses `eval', the
code also uses functions like `make-namespace' and
`namespace-set-variable-value!' to explicitly install bindings into the
top-level environment.

Use -u instead. Here's a longer explanation:
