The simplest way to implement such a thing is using
functions like scm_c_eval_string, where one creates a string
containing Guile code and executes it.

There are more complicated strategies that might be slightly faster.
One could get a variable that contains a procedure by using
scm_c_public_lookup.  Then, the procedure itself can be extracted
by using scm_variable_ref.  And it can be called using
The scm_call_0, scm_call_1 family of functions.

There is an example in the manual here
