D2 is really that stable as it is claimed to be?

Regarding the improving the error messages of D compilers, I 
think having the column number is nice, but there are two 
improvements that I think are more important:

1) One of them is the "aka", that is showing both the name of 
aliases and the aliased types/values:

2) The other improvement I'd like for D error messages and 
warnings is to give a standard error number. This is a simple 
improvement, but it makes simpler to write explanation pages for 
the errors. The C# compiler and other compilers have them.
