Sure. In Larceny/x86, however, files are compiled anyway when you load them, so the main motivation for compiling files separately is to make them load a lot faster. > Is there a form to load only the macros from a file?

The files that don't contain any macros can be compiled using compile-file. The next public release of Larceny is likely to have some kind of support for loading R6RS libraries into Larceny's R5RS top level. That will become the new preferred way to structure libraries in Larceny, but it won't be as portable as the separate files unless and until ERR5RS catches on [1]. > from searching the net I gather that larceny has more > to offer than plain syntax-rules, but I can't find any > documentation.

As an example of explicit renaming, you might look at Lars Hanson's implementation of defmacro [3]. The next public release of Larceny may support Andre van Tonder's explicit renaming macros, which are an improvement over Larceny's. These macros would be available only within R6RS libraries, but you will be able to load those libraries into an R5RS top level.
