anonymous functions?

[Bill Schottstaedt]

I'm using scm_make_procedure_with_setter, but would like to pass it
"anonymous functions" -- I'm currently using the function name "",
which appears to work, but I worry that this method has not received
a proper blessing:

gh_define(function_name,
  scm_make_procedure_with_setter(
    gh_new_procedure("",get_function,1,0,0),
    gh_new_procedure("",set_function,2,0,0)));
