This also permits the system + to warn on static type mismatches and function + redefinition. (Currently it does not work with high DEBUG level.) + * minor incompatible change: VALUES declaration is disabled. + * When issuing notes, the compiler now signals a condition of type + SB-EXT:COMPILER-NOTE, and provides an associated MUFFLE-WARNING + restart for use in user handlers. It is expected that the + COMPILER-NOTE condition will eventually become a condition + supertype to a hierarchy of note types, which will then be + handleable in a similar fashion. However, at the moment, no such + note subtypes yet exist. (SB-INT:SIMPLE-COMPILER-NOTE exists, + but it's an implementation detail, not a classification for the + purpose above.) + * Changes in type checking closed the following bugs: ** type checking of unused values (192b, 194d, 203); ** template selection based on unsafe type assertions (192c, 236); ** type checking in branches (194bc). - * VALUES declaration is disabled. - * a short form of VALUES type specifier has ANSI meaning. + * A short form of VALUES type specifier has ANSI meaning (it has + increased the number of situations when SBCL cannot perform type + checking). * fixed bug in DEFSTRUCT: once again, naming structure slots with keywords or constants is permissible. * STREAM-READ-SEQUENCE and STREAM-WRITE-SEQUENCE now have methods defined on the relevant FUNDAMENTAL-BINARY-{INPUT,OUTPUT}-STREAM classes. (thanks to Antonio Martinez) - * bug fix: APROPOS now respects the EXTERNAL-ONLY flag.

(reported by Raymond Toy) + * bug fix: In macro-like defining macros/special operators the + implicit block does not enclose the lambda list. + * fixed bugs 10 and 43: Bare VALUES, AND, OR and MEMBER symbols (not + enclosed in parentheses) are not suitable as type specifiers, and + their use properly signals an error now. + * bug fix: An argument count mismatch for a type specifier in code + being compiled no longer causes an unhandled error at compile + time, but signals a compile-time warning. + * fixed simple vector readable printing + * bug fix: DESCRIBE takes more care over whether the class + precedence list slot of a class is bound before accessing it. + (reported by Markus Krummenacker) + * bug fix: FORMATTER can successfully compile pretty-printer format + strings which use variants of the ~* directive inside. + * bug fix: SEARCH now applies its TEST predicate to the elements of + the arguments in the correct order.

Brown) + * bug fix: Reading in symbols with an explicit package name of "" + (e.g. '||::FOO) now works correctly.

This means that a declaration + (TYPE (ARRAY FOO) BAR) means that, within the scope of the + declaration, all references to BAR will be asserted or assumed + (with THE, so dependent on compiler policy) to involve objects of + type FOO.
