distinguishable from memoizing macros created on the scheme level or from user provided primitive memoizing macros. The reason is, that the internal memoizers are the only ones that are allowed to transform their scheme input into memoizer byte code, while all other memoizing macros may only transform scheme code into new scheme code. To achieve this, a new macro type 'builtin-macro!' is introduced. Currently, 'builtin-macro!'s are handled as memoizing macros, but this will change when the memoizer and executor are separated. * macros.[ch] (scm_i_makbimacro): New. * macros.h (SCM_BUILTIN_MACRO_P): New. * macros.c (macro_print, scm_macro_type): Support builtin-macro!s. * eval.c, goops.c: All of guile's primitive memoizing macros are primitive builtin-macros now. * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive builtin-macros are handled equally to memoizing macros.
