Is *explicit* better than implicit?

I feel that there is an almost unanimous agreement on that `implicit none` must be mandatory, but I guess many of you will provide interesting _exceptions_, so

In the case you disagree, please elaborate your idea.

Review the issue's 66-comment discussion to understand the competing views on whether explicit coding practices, including `implicit none`, should be advised. Done means reaching a clear decision and documenting the agreed guidance; no file or test is identified in the issue.
