Too definitive to my palate, sorry.

You may wish reading the recent long discussions of what is/should be
and what isn't/shouldn't be immutable.  Turns out some of us are very

"make sure you know what you are doing" is what actually is the truth.

Once again, we are not talking to kindergarten kids.
