I suggest to remove the "-w" switch from the list of dmd/ldc2 switches, and later to remove that functionality too. It's better to keep only the informational warnings.

I keep seeing people in D.learn that miss warnings because they don't active them, so I suggest to activate informational warnings on default.

And then I suggest to add a switch to disable the warnings, for the rare situations where you don't want them.

This might increase knowledge like you say. Plus, you'd have warnings about stuff like implicit switch case fall-through as the default. I think this idea sounds okay.

I think a "strong, silent type" of D compiler is not the best.
Maybe Walter can offer an opinion, even negative :-)

I've been using D heavily for well over a year now and I've never used -w (facepalm)
That's good anecdotal evidence that it should be opt-out not opt-in.

Brb... Recompiling all my code with -w to find out my stupid mistakes :p

If you seem my first point, I am suggesting to remove "-w" from the switches and to use "-wi" (actually I am suggesting "-wi" to become the default compilation mode).

Regardless of any FR's I still want to ability for compilation to halt on a warning, even if it means a new switch. As for the whole -w/-wi thing, why can't people just read the list of switches?

It's a fair desire, but for it probably the problems in Issue 10321 need to be faced first.

I have seen tens of times that this doesn't happen, in D.learn, in #D on IRC and with friends, students, etc. Silent compilers that keep the muzzle shut on default are not good enough. John Colvin's answer is not so unusual.

I have aggregated a request of mine to your issue 10147. Are you OK with this? (What I am asking in addition to your request is for informational warnings to be active on default and to be disabled on request.)

I've added a reply to the bugzilla issue, I think I might not even need this behavior anymore, so I withdraw the request.
