scm_c_lookup gives you a variable object, as you note below; better to
call it `funcVar' (or `func_var' if you're shift-impaired :)

If the var is unbound, scm_c_lookup will throw, no need for error
checking. Also perhaps you were looking for scm_is_false (func_var); see
the section entitled "Dynamic Types" in the manual.

Likewise don't return 0 as a SCM

This part is right :-)
