I would like to know the correct way to fail the creating of an object.
I would return a NULL in c/c++ but returning a nil does not to seem to
work correctly i.e.

if(obj) then do stuff

OR

if(obj != nil) then do stuff

New to Ruby if you couldn't guess.

the code is easier to work with if it either returns valid results, or
raises
an exception - i removes the burden of testing return values in the
client
code.

kind regards.

Thanks for quick response, I decided to do error testing before creating
object thus removing the problem, I find exception handling messy.

Thanks,
Jim.
