Just a lazy note, don't take this too much seriously.
The Computer Language Benchmarks Game (Computer Shootout) has added some
Clojure implementations, they are not tuned and refined yet (probably unlike
the Free Pascal versions). This is one of the problems ("fasta"), there are two
Free Pascal and two Clojure implementations:

The Clojure versions currently use about 370_000 KB of RAM to run, their source
code is about 1_600 compressed bytes long, and their run time is about 30-38
seconds.
The Free Pascal versions use about 250 KB of RAM, their compressed source code
is about 1_100-1_200 bytes long, and their runtime is 8-12 seconds.
I have written many small programs in Scheme, but for me that Free Pascal code
is more readable than that Clojure code. Probably Free Pascal lacks some of the
cool new features of Clojure (including a garbage collector), but I don't see
much progress in languages development/hystory here ;-)
A question: Here for example the cheapest C program uses 452 KB of RAM. On
average in the Shootout benchmarks Free Pascal uses less or quite less RAM than
the D programs. Do you know why the Free Pascal programs use so little RAM?
