Oh... please forget it
What a terrible example :p I forgot why I was using pointers at
all... I must have had a reason to write this in the past ???
I do not really think it's a bad solution, to check several
scalar arguments that must obey the same condition; just
wondering if you have better ideas. Try to avoid modifying the
function's signature and defining custom types, unless you have a
really terrific idea.

What behavior is a rhetorical question, meaning that I don't
really want it to be answered 0;)

Just wrap it in a @trusted function.
I knew this answer already of course ;) but I take it as implying
that there is no other way.
Actually I really wonder why std.stdio.readln() itself is not

The same way as T.foo() is lowered to foo(T) if no such member is
defined inside the type. It would allow me to extend 3rd party
types with operator notation without wrapping them.
After trying and reading the specification, looks like nuts, but
just wanted to confirm. Thx
I was surprised by a compiler message saying that
std.stdio.readln() (and specifically the overload without
arguments) is not safe but @system.
Actually I was using it only to pause execution until the user
presses Enter. So how else could I do this within a @safe
environment?
And more
Andrei's 2010 book states that the default safety level can be
changed from @system to @safe by means of a -safe command line
switch, in the case of the DMD compiler. Now I've tried it and
it's not recognized.
Was this feature remove on purpose? I could imagine that.
The default safety keeps

On the command line it seems to be possible to specify debug
