I did not want to imply, that this is **your** opinion. Sorry, for the
Just two points I would like to mention:
1) The above given definition practically makes the exception family
based on logic_error useless. This is even documented in the Our
Standard. 19.1.1/p. 1 says:
"The class logic_error defines the type of objects thrown as exceptions to report
detectable before the program executes, such as violations of logical
preconditions or class invariants."
2) For what kind of errors should be BOOST_ASSERT for? My
assumption is, it is for what you name "programmer error". If so,
shouldn't it actually provide the throw() guarantee? I think, many of
you would like to kill me for this proposal ;-), but for me it seems like
a natural conclusion.
