Since these discussions are uselessly abstract and meta
Here is some code I (tried) to write in class the other day
The basic problem is of generating combinations
Using the pascal-identity nCr + nC(r-1) = (n+1)Cr
This can be written (Haskell)
c :: Int -> Int -> Int
c n 0 = 1
c 0 (r+1)

If you see the "semantics are equivalent" Steven wins.
If you focus on "like other languages" then it's... well not quite equivalent!

The first book I studied as a CS-student was Structured Computer Organization

Apart from the detailed description of various machines like PDP-11, IBM-360
etc it suggested the understanding of the computer at 4 levels:
- Microprogramming level
- "Conventional" machine level
