[cffi-devel] Re: setf-expander of FOREIGN-SLOT-VALUE

The setf-expansion for nested FOREIGN-SLOT-VALUE calls ist not quite correct:

should do the job a bit better, though it might be optimized in some way (this is my first try to define a setf expander).

Thanks, I'll have a look at this tomorrow. I need to read define-setf-expander's docs, heh. /My/ first try to define a setf expander was mem-aref's and that was just by looking at mem-ref's expander.

Btw. the manual contains an example use of FOREIGN-SLOT-VALUE with the simplified syntax

(foreign-slot-value ptr 'struct 'slot-1 'slot-2)

I think CFFI has all the informations at hand to handle this, so will it be implemented one day?

Yes, one day. :-)
