Clozure CL (CCL) is a Common Lisp implementation. It implements the full ANSI Common Lisp standard with several extensions ( CLOS MOP , threads, CLOS conditions, CLOS streams, ...). It contains a command line development environment, an experimental integrated development environment (IDE) for Mac OS X using the Hemlock editor, and can also be ...
Several Common Lisp implementations (like Clozure CL and SBCL) are implementing eval using their compiler. This way code is compiled, even though it is evaluated using the function eval. The file compiler is invoked using the function compile-file. The generated file with compiled code is called a fasl (from fast load) file.
[3] [4] The main point of divergence at the time was a clean bootstrapping procedure: CMUCL requires an already compiled executable binary of itself to compile the CMUCL source code, whereas SBCL supported bootstrapping from theoretically any ANSI-compliant Common Lisp implementation. SBCL became a SourceForge project in September 2000. [3]

2 SbCl 5 + 5 H 2 O → Sb 2 O 5 + 10 HCl. The mono- and tetrahydrates are known, SbCl 5 ·H 2 O and SbCl 5 ·4H 2 O. This compound forms adducts with many Lewis bases. SbCl 5 is a soft Lewis acid and its ECW model parameters are E A = 3.64 and C A = 10.42. It is used as the standard Lewis acid in the Gutmann scale of Lewis basicity. [8] [9]
Lisp evaluates expressions which are entered by the user. Symbols and lists evaluate to some other (usually, simpler) expression – for instance, a symbol evaluates to the value of the variable it names; (+ 2 3) evaluates to 5. However, most other forms evaluate to themselves: if entering 5 into Lisp, it returns 5.
CL programmers use the language's package facility to declare which functions or data structures are intended for export. Apart from normal ("primary") methods, there also are :before, :after, and :around "auxiliary" methods. The former two are invoked prior to, or after the primary method, in a particular order based on the class hierarchy.
Hemlock is a free Emacs text editor for most POSIX-compliant Unix systems. It follows the tradition of the Lisp Machine editor ZWEI and the ITS/TOPS-20 implementation of Emacs, but differs from XEmacs or GNU Emacs, the most popular Emacs variants, in that it is written in Common Lisp rather than Emacs Lisp and C—although it borrows features from the later editors.
