Hard to say :) What versions of Emacs and Geiser are you using? What
scheme and version?  How did you install Geiser?

Geiser starts a REPL and then sends messages to it using the evaluation
functions in geiser-eval.el.  Those functions take either scheme strings
or sexp-based DSL: the reason it's not pure scheme is that it uses
tailored evaluation functions, telling the underlying scheme in what
namespace the given expression should be evaluated, and also having
shortcuts for some pre-defined Geiser functionality such as autodoc.

If you take a look at geiser-eval.el and experiment a bit with the
functions there, there shouldn't be too difficult to get the gist of
it... but it's not documented, so please feel free to keep asking around
here.

Cheers,
