I shall add that the larger the project, the more libraries one usually relies on, and the higher the risks of incompatibilities. It is not uncommon for a 20,000 lines project to rely on 5 or 10 libraries. 
What is the probability to find 10 libraries compatible with each other and with the latest compilers in the D codebase right now ?
