I'm not sure what you have in mind here. I made this with Guile, making an 
infix language on top of it. When the new language program starts, it calls 
init_guile() and reads an input, constructing a Guile expression through calls 
to the Guile header objects, after which it is evaluated using 
scm_primitive_eval().
