So basically, this is saying "If your C code compiles in D,
you'll get the same result. I guarantee it :)"
It's a general rule, but it has some exceptions, like C programs
that rely on global floating point variables initialized to 0, or
when you use a fixed-sized array, that D passes by value and C by
pointer.
Here's a (reduced) C program:
----
int i = 3;
void main()
{
{
int some_condition = 1;
if ( some_condition )
goto block_end;
/* dummy code */
} block_end:
{
int i = 7;
printf("%i", i);
}
printf("%i", i);
}
----
C prints: "70"
D prints: "77"
This should go in some page that lists the differences between C
and D.
if anybody can think of a rationale for the current behavior.
And if there is no rationale, how much support there is for
changing it.
It's bad to break C backwards compatibility for free, so if it's
not useful for D then and it should be fixed.
