In case we need to put it on punch cards? :smirk: 

I don't think the 80 limit should be a hard rule. To me readability is the most important part of writing code. In this case its just a string for the error message. Busting up the message into multiple lines to me hurts the readability.

As another example in the test code for enums they go over 80 on quite a few occasions. But because of how the code is structured its much more readable than having multiple lines.

Could we just have a line length within reason rule? I do try to get things under 80 but in some cases I think its better to let the code go a little longer if it helps readability.
