[Coin-discuss] exception specifications

[Laszlo Ladanyi]

Hi Matt,

I looked at the page Matt pointed to (and searched a bit elsewhere, too), and
the reasons for NOT to have exception specification in the code is fairly
compelling. I propose to remove them all. According to the docs I found this
should not break the compilation of any existing code relying on COIN code.
Could people verify this? If really nothing breaks and noone comes up with
other reasons for having the exception specifications then I'll remove then at
the end of March.

As I understand it, if you miss an exception specification, this can cause run-time errors that should otherwise work fine. Identifying exceptions (for the sake of the user) can simply be done with documentation (comments), rather than in the prototype.
