There's no usage of an undeclared variable, but the right-hand-side of
the
second line uses 'i' before *the programmer* initializes it. Yes, the D
compiler chooses to automatically initialize it, but by doing so it
silently
creates a bug every time the programmer intends 'i' to start out as
anything
other than 0. And it's not easily noticed since 0 is a commonly-used
value.
(Something like 0xDEADBEEF would at least be an improvement (albeit a
small
one) since at least that would stand out more and likely fail more
spectacularly.)
So you want language force you to type either "int x=0;" or "int x=void;".
Fair enough and i agree it "might" be a bit better. But you are making it
as it is something so much important.
Again, for both coder and the code-reader there is no ambiguity here,
every single thing is defined.
