on libraries

R⁷RS leaves it unspecified how exactly libraries correspond to files:

Programs and libraries are typically stored in files, although in some implementations they can be entered interactively into a running Scheme system. Other paradigms are possible. Implementations which store libraries in files should document the mapping from the name of a library to its location in the file system.

thus the implementation of define-library is open to much interpretation. we could possibly define libraries as first-class objects, or deal with them statically. the former case is appealing to me, as it could massively simplify interactive use.
