Symbolics could have built computers with custom hardware. At some point in time the 64bit RISC CPUs (MIPS, Alpha, SPARC, POWER, x86-64, ...) were all powerful enough to run Lisp. Genera got ported to the DEC Alpha). They would have been al

There are a bunch of reasons. But the three main reasons: * the Xerox Lisp Machines were limited: very small address space, slow, expensive. Most projects very early on reached the limits of these machines. A Symbolics would be even more ex

The actual LISP 2 project to update LISP 1.5 (also conceptually, for example with a new syntax) was done in the mid 1960s. It was famous for its failure. From 2017 is the work done to collect historical documents, source code, etc. about th

In the early days the CPUs had loadable microcode. With new operating system versions came language extensions for Lisp. Then one also got a new version of the microcode, which then had been extended for, say, inclusion of an instruction fo

The Genera code for ARM64 and Intel 86-64 is also written that way. Clozure CL should also include an inline assembler. Lisp assemblers date back to the 60s.

Gary Palter has made it work both on Linux and macOS, both x86-64 and ARM64. He also brought the original Open Genera for DEC Alpha to the same software level.

I would think that in the few remaining CPUs specially designed to run Lisp have a significant historical value. Just having a working original Lisp Machine is extremely rare these days - given that there were probably only 10000 ever being

That's not how Lisp works. Lisp macros don't operate on an AST.

The term "Lisp" is undefined. Common Lisp is an actual standard for a programming language with a specification. Its core symbols are reserved identifiers. Anyway, if you would be allowed to reimplement a built-in operator, then f

s-expressions can provide a hierarchical structure, but they are not representing AST. It's just another form of source code. > And, of course, an interpreter that works by walking S-Expressions is really, really slow. Common Lisp i

In Common Lisp the identifiers in package Common Lisp are not allowed to be redefined.

Check the Common Lisp specification some time. Every language construct has a syntax definition: function calls, macro calls, lambda expressions, special operator calls, ..., every macro.
