There are three patterns that need to be supported:

1) Compile an R7RS library

2) Compile or interpret an R7RS main program (with the ability to import
at least R7RS libraries, and preferably Chicken libraries too)

3) Run an R7RS REPL or interpret an R7RS script (not a standardized idea,
but very useful)

The difference between (2) and (3) is that in a main program, no
identifiers are initially available except `import`, and everything else
has to be imported; in a script, at least (scheme base) is available, and
whatever else seems like a good idea, standard or non-standard, should be
available too.  AFAIK Chicken has nothing corresponding to main programs.
