Comment:
I still haven't found this warning in http://www.boost.org/libs/random/
random-distributions.html#uniform_01 and encountered the same problem.
Please make clear that drawing a number from uniform_01 will NOT change
the state of the passed generator. And why to pass the generator as a non-
const reference if it is not being changed?
I suggest making the constructor argument (the reference to the generator)
of uniform_01 const and pointing the users to uniform_real which works as
expected (changes the state of the generator after drawing a number).
