The FLI type
ns-rect
is a structure type for use as the Objective-C type

. The structure has two slots,
:origin
of foreign type ns-point and
:size
of foreign type ns-size.
When used directly in method definition or invocation, it allows automatic conversion to/from a vector of four elements of the form
#(
x
y

)
.
