U= sually, sure, but in the code =E2=80=98#:to =E2=80=98value=E2=80=9D was set= . From the manual:

>As discussed before (see > * Value

Now, as example it comp= iled a lambda expression into a procedure, but it can be done for Scheme ex= pressions that don=E2=80=99t evaluate to procedures as well. The definition= =E2=80=98(define a whatever)=E2=80=99 strictly speaking isn=E2=80=99t an e= xpression, but it appears the compilation stack doesn=E2=80=99t care.<= /o:p>

 

>alternatively, you yourself can exp= licitly call the lambda returned by compile.

 

In this particular case, no lambdas are returned.<= o:p>
