I agree. Breaking the rules was mainly the reason for the drop. Entries
like chameneos and fasta. Also, the other language teams kept improving
Other language (perl, iirc) were affected far worse by the gzipping.
gzip is an interesting measurement, and it doesn't hurt Haskell too much
either way -- short Haskell programs stay short when compressed.
As a result, rewriting verbose entries to ByteString will probably be
much more useful :)
Btw, Isaac, are we going to have any new parallelism benchmarks? I'd
love to try out the SMP runtime ;)
