Hello,

I realize that this library is not yet part of the boost distribution but I am using it and have come accross an issue.  I am concerned that the logic in the various check functions may be flawed.  Take for example the check_uniform function.  The logic is as follows:

if  lower Ok && upper Ok && lower < upper

     return true

else

     raise error stating that lower must be less than upper
     return false

end if

The functions used to determine if lower and upper are ok will raise errors if appropriate.  If the policy is such that raising an error does not cause a throw, then control will return to the check_uniform method with an indication that lower or upper is not ok and we will enter the else block.  Herein lies the problem.  Consider the following scenario:

creating a uniform distribution with:

lower = 0.0
upper = postitive infinity

Check upper will fail and send a message about the infinity.  Enter the else block.
A message will be raised that states that the lower parameter is not less than the upper.

This is my concern.  I believe the second message is unnecessary and potentially incorrect/misleading.  Perhaps logic like shown below would be more appropriate:

if lower not Ok || upper not Ok then

     return false

else if lower >= upper

     raise error stating that lower must be less than upper
     return false

else

     return true

end if

Thanks,
John
