Dear Haskell-Primers (and libraries).
Recently, Phil Wadler has pointed out a weird anomaly in the Haskell'98
Prelude, regarding numeric enumerations for Floats/Doubles:
Prelude [0, 0.3 .. 1.1]
. Floating
point numbers are not the real numbers, and the sooner they learn that
the better. We can fudge this all we like, but 0.1 is never going to
be exactly representable as a binary floating point number no matter
what we do.

Silly me! I didn't even think to try! Nice. And thanks!

rather crude way of doing this. On the other hand, I suppose that this
could also provide a reference implementation of asynchronous exceptions
for any Haskell' that supports concurrency...

behavior sounds nicer, but I'd rather there were the
possibility of naming our haskell files whatever we liked. Currently, as
far as I can see, we can only do this with Main, and even then there are
weirdnesses in ghc because Main.hi gets generated.
