[Chicken-users] Conditional expansion: #+

[j . romildo]

Hello.

The stalin.scm source file, from the stalin egg, starts with

   #+(not csi)
   (include "QobiScheme")
   (include "architectures.scm")

According to the manual,

   #+FEATURE EXPR

is the conditional expansion, a non-standard read syntax, and it is
equivalent to

   (cond-expand (FEATURE EXPR) (else))

Therefore the code above should be equivalent to

   (cond-expand
    ((not csi) (include "QobiScheme"))
    (else))

   (include "architectures.scm")

Is that right?

If so, maybe stalin.scm should not be implemented this way.

For what I understand, stalin is not supposed to be run from the Chicken
interpreter. So the conditional expand shoud avoid compiling the whole
file, no only the first include form.

Any comments?
