address@hidden stack allocated Lisp objects
address@hidden Lisp objects, stack-allocated
   The garbage collector described above is used to manage data visible
-from Lisp program, as well as the most of data internally used by the
-interpreter.  But sometimes it may be useful to allocate temporary
-internal (i.e. not visible for Lisp program) objects using C stack of
-an interpreter.  Currently conses and strings are the only objects which
-can be allocated in that way.  Strings are limited to ASCII characters
-only and should be treated as immutable (calling @code{ASET} on them is
-undefined).

address@hidden stack allocation internals
-  In C, this is implemented as a special macros which expands to
-a @code{Lisp_Object} with block-scoped semantics and lifetime (see
-the code around @code{USE_STACK_LISP_OBJECTS} in @file{lisp.h}).  This
-means that these objects are not managed by the garbage collector;
-instead, they are allocated like local variables in C and automatically
-freed when an execution reaches an end of the corresponding scope.  Thus,
-allocation and freeing are faster than using garbage collector.  But
-remember that passing them out of their scope results in undefined
-behavior.  Think twice before using this feature and carefully debug
-your code with @code{GC_CHECK_MARKED_OBJECTS} (see @file{alloc.c}).
