alisp is an implementation of Common Lisp that covers a good part of the standard.  It ships with ASDF and is capable of loading many real-world systems.

Version 1.6 is out!

Here are the news:

- Specialized arrays have been completely redesigned.  Now strings and bit vectors are just instances of byte arrays, that in the future will be also used for arrays specialized to integers of various size.  This change has seemingly caused a regression: now strings are byte-based and so Unicode is not handled anymore; but Unicode support will come back in due time in a different fashion

- (SETF GETF) was pretty much broken, now it has been fixed.  (SETF GET) has been added

- MAKE-SEQUENCE has been added

- Now DEFPACKAGE supports the option :SHADOWING-IMPORT-FROM, so it's pretty much complete

- Now structure slots support initialization forms

- The new implementation in lisp of DEFCLASS had a bug: it defined accessor methods without type specializers: this caused subtle bugs when two different classes had an accessor with the same name for fields of different names.  Of course, ASDF did precisely that.  Now it's been fixed

- A recent regression has been fixed: now user-defined conditions can be raised again

- Generic functions SLOT-MISSING and SLOT-UNBOUND have been added

- INTEGER-LENGTH and LOGCOUNT have been added

- LAMBDA and IN-PACKAGE have been moved to lisp code

- Other minor fixes and enhancements
