Yes I see now (https://dlang.org/spec/contracts.html):  "It is 
important to ensure that the code has no side effects, and that 
the release version of the code will not depend on any effects of 
the code. For a release build of the code, in and out contracts 
are not inserted."

I really didn't see this paragraph (I was looking for a flag for 
"removing" in/out assertions at compile time).  My fault!!!
