[Ecls-list] Gray streams

[Juan Jose Garcia-Ripoll]

Tag: (CVS 2008-03-17 17:51)

 - Gray streams are now implemented in a separate package, called GRAY, which
   exports symbols such as FUNDAMENTAL-STREAM or STREAM-READ-CHAR.

 - The functions CLOSE, {OPEN,INPUT,OUTPUT}-STREAM-P, STREAM-P and
   STREAM-ELEMENT-TYPE are now offered in two flavors. The versions exported by
   the COMMON-LISP package are ordinary functions, the versions in the GRAY
   package are generic functions that can be specialized to new classes. The
   ordinary functions will invoke the generic version when passed a generic
   stream. Note that, for instance, CL:CLOSE and GRAY:CLOSE are not the same
   symbol. This means you might need to shadow-import the symbols associated to
   generic versions in the packages where methods on these functions are
   defined.

The change of package name, which is essential to provide the generic
functions, might break code that imported these classes from the EXT
package.
