Lisp is a programming language that dates back to 1958, initially conceived as a means to mathematical notation, was later adopted as the to-go language for artificial intelligence.
As it's name indicates, Lisp ("LISt Processor") works on a syntax composed of lists for data as well as for expressing code; which seems intimidating at first, but it's quite pleasant when you get used to it.
It has a powerful macro system that let's the programmer extend the language and create domain-specific languages.
SBCL 1.1.14 was used for running the tests.
How fast does the interpreter loads and parses the source code.
$ time sbcl --script lisprb.lisp real 0m4.911s user 0m0.484s sys 0m0.048s
Starting up sbcl seems to be avery slow operation. I don't think that parsing the program would be responsible of the slow loading times.
$ time sbcl --script lisprb.lisp real 24m43.216s user 24m27.772s sys 0m4.972s
Line count: 131 code, 30 blanks, 161 total.
File size: 5833 bytes.
For several years, I've had Lisp in the radar. Many stories have I read of teams succeeding while using this programming language when deadlines and/or budget where critical, so that picked my interest.
After working with it for this project, I find Lisp very pleasant to work with, the syntax is nice and very expressive. Too bad I didn't make use of the macros system (which I couldn't find a good use case for).
