Hugs [3,7..22]
[3,7,11,15,19] - OK
Hugs map (* 1.0) [3,7..22] - same spec as first but !!! when
mapped to with a
(*1.0) to coerce
them to reals:
[3.0,7.0,11.0,15.0,19.0,23.0] - went one
An easier way of demonstrating this issue:
Prelude [3,7..22]::[Int]
[3,7,11,15,19]
Prelude [3,7..22]::[Double]
[3.0,7.0,11.0,15.0,19.0,23.0]

The problem I see is that in both:
Version: September 2006 of hugs, which is the one that is current for
Ubuntu 9.10 release, and
ghci 6.10.4, they both exhibit a {I think} strange behaviour, in regards
to the shorthand way of calling out a list of enumerable values. I will
explain the problem

From the Haskell 98 report (section 6.3.4):
For Float and Double, the semantics of the enumFrom family is given by the
rules for Int above, except that the list terminates when the elements become
greater than e3+i/2 for positive increment i, or when they become less
than e3+i/2 for
