abcl-1.3.3 currently includes code in the ABCL-CONTRIB mechanism for two
such additional syntaxes, namely [JFLI-ABCL][1] and [JSS][2].

[1]: http://abcl.org/trac/browser/trunk/abcl/contrib/jfli/README
[2]: http://abcl.org/trac/browser/trunk/abcl/contrib/jss/README.markdown

One may load these packages by

```lisp
(require :abcl-contrib)
(require :jfli)
```

or

```lisp
(require :abcl-contrib
(require :jss)
```

I don't really know much about JFLI, but use JSS extensively.

The example of
```lisp
(-> |Main.addTwoNumbers| 2 4)
```

would become

```lisp
(#"addTwoNumbers" 'Main 2 4)
```

in JSS.
