Andrei Alexandrescu:

We've just enabled warnings as errors in our build system at work and suddenly:

It's much better to enable warnings since day -1, that means the day before you start creating your D project. That's why I'd like D compilers to have warnings active on default and to have a switch to disable them on request (Walter has not yet answered about this idea).


What's the idea?

The idea is to tell well apart the assignment of values (like scalars and fixed size arrays) from slice assignments. In general if you have a vector operation, use a []. There are corner cases (with arrays of arrays, fixed sized arrays of dynamic arrays, etc), that if you don't use such strict syntax, lead to undefined (ambiguous, weird) situations. The warning helps avoid that problem, and the warning will be replaced by a deprecation later.

Bye,
