It seems that Hugs, ghc, and hbc all give the same wrong answer,
as mandated by the Haskell report. nhc98 alone gives the expected
answer of [0.0, 2.0, 4.0, 6.0, 8.0], but thereby breaks the standard.
So I echo the question:

Then either I must fix nhc98, or everyone else must fix ghc, Hugs,
hbc, etc.
