[slime-devel] [PATCH] more reader cleanups

[Tobias C. Rittweiler]

* make-d-macro-char.diff

   Currently, invoking MAKE-DISPATCH-MACRO-CHARACTER on a character
   that's already been made a dispatch macro character results in an
   error.

   All other implementations I tested, do not signal an error, but just
   override a possibly existing dispatch table.

   I think that's sensible, as the the CLHS entry for MAKE-D-M-CHAR says
   Exceptional Situations are None.

* get-dtable-pair.diff

   The implementation for retrieving an entry from the dispatch tables
   is currently duplicated on all call sites.

   This patch introduces an explicit getter function.

   Also, in SET-DISPATCH-MACRO-CHARACTER the function argument was
   COERCED to a function (thus allowing literal lambda expressions), use
   %COERCE-TO-CALLABLE instead.

* inline-assert-not-std-rt.diff

    Inline ASSERT-NOT-STANDARD-READTABLE, and MAKE-DISPATCH-CHAR-TABLE.

* char-attr-table-type.diff

    Introduce an explicit type for character attributes (CHAR-ATTR), and
    rename the type ATTRIBUTE-TABLE to CHAR-ATTR-TABLE.

* ref-cat-entry.diff

    Fix more FIXMES and code duplication by introducing a low-level
    getter REF-CAT-TABLE which is then used at the appropriate places.
