The code below fails to compile with
Error: function `test1.foo` no `return exp;` or `assert(0);` at
end of function
unless the commented-out assert(0) is included.
Please, what rule of D is being broken?
foo does not unconditionally loop, and the only places where foo
returns, it returns with a bool.
```
bool foo() {
import std.stdio;
int I1;
int nogoagain;
while(true) {
I1 = 2;
while( I1 <= 10) {
if (I1 != 5) {
} else {
goto L2;
}
I1 = I1 + 1;
}
return true;
L2:;
readf(" %s", nogoagain);
if (nogoagain == 5) {
return false;
} else {
}
}
// assert(0);
}
void main() {
import std.stdio;
writeln("A");
writeln(foo());
}
```
