"debian coding contest" ?
It's been called many things but, until now, not that.

Tiny tiny toy programs - more or less 100 lines - not quite small enough to be microbenchmarks. Why might that be?
Well, not IO bound. Do people usually mean IO performance when they compare programming languages?
(I guess you must have excluded meteor-contest from your consideration. It's a coding contest and so doesn't specify an algorithm.)

binary-trees - No, it doesn't say that.
thread-ring - No.
chameneos-redux - No.
pidigits - No.
regex-dna - No.
k-nucleotide - No.
mandelbrot - No.
reverse-complement - No.
spectral-norm - "Each program must implement 4 separate functions / procedures / methods like the C# program." (The point being cross function calling so don't amalgamate 4 functions into a single function.)
fasta-redux - No.
fasta - No.
meteor-contest - No.
fannkuch-redux - "defined by programs in Performing Lisp Analysis of the FANNKUCH Benchmark"
n-body - "Each program should model the orbits of Jovian planets, using the same simple symplectic-integrator - see the Java program."

Probably not too onerous a requirement for a test of hash table lookup :-)
Some people like hash tables, go figure.

Too obvious to be interesting.
Interesting that you haven't said how you know they are "designed to favor imperative languages" ;-)
