Armed Bear Common Lisp (ABCL) implementation of the Common Lisp language in the JVM.

Armed Bear Common Lisp (ABCL) is a full implementation of the Common Lisp language featuring both an interpreter and a compiler, running in the JVM (Java Virtual Machine). ABCL supports the JSR-223 (Java scripting API): It can be a scripting engine in any Java application. Additionally, it can be used to implement (parts of) the application using Java to Lisp integration APIs. ABCL, documentation, etc. are available here.

In Allegro CL and ABCL, can I construct a struct given only its type name?

In most implementations, you can use (make-instance 'struct-type) to create a struct regardless of whether you defined a constructor function for that type. This doesn't work on Allegro or ABCL, but those implementations can still create structs at…
