It was drawn to my attention that SDWF refuses to compile under DMD
0.106. Though there was one thing genuinely wrong with my code, fixing
this thing revealed even more things wrong with the compiler.
1. Anonymous structs/unions refuse to work, whether in a class or in
module scope.
----------
import std.stdio;
struct {
int qwert;
}
void main() {
writef(qwert);
}
----------
D:\My Documents\Programming\D\Tests\bugs\broken106_struct.d(8):
undefined identifier qwert
----------
2. Moreover, if a class has an anonymous struct/union, any attempt to
initialise any of the members causes trouble:
----------
class Qwert {
struct {
int yuiop = 13;
}
int asdfg = 42;
}
----------
D:\My Documents\Programming\D\Tests\bugs\broken106_init.d(1): class
broken106_init.Qwert 2duplicate union initialization for asdfg
D:\My Documents\Programming\D\Tests\bugs\broken106_init.d(1): class
broken106_init.Qwert 2duplicate union initialization for yuiop
----------
3. Private members of nested classes are not accessible, either from the
containing class, other classes in the module or other global functions
in the module.
----------
class Qwert {
this() {
Yuiop asdfg = new Yuiop;
asdfg.hjkl();
asdfg.zxcvb = 69;
}
class Yuiop {
private {
this() {}
void hjkl() {}
int zxcvb;
}
}
}
void main() {
Qwert.Yuiop asdfg = new Qwert.Yuiop;
asdfg.hjkl();
asdfg.zxcvb = 105;
}
class Nm {
this() {
Qwert.Yuiop asdfg = new Qwert.Yuiop;
asdfg.hjkl();
asdfg.zxcvb = 666;
}
}
----------
D:\My Documents\Programming\D\Tests\bugs\broken106_private.d(3): class
broken106_private.Qwert.Yuiop member this is not accessible
D:\My Documents\Programming\D\Tests\bugs\broken106_private.d(4): class

D:\My Documents\Programming\D\Tests\bugs\broken106_private.d(27): class
broken106_private.Qwert.Yuiop member zxcvb is not accessible
----------
I invite you all to post any other bugs that have newly appeared in
0.106 as followups to this thread, to keep them all together.
Especially those that (like these) have prevented existing projects from
compiling or running correctly.

But in this instance, it should either work or complain about a syntax error, not an undefined identifier. As for how I'm using it, SDWF has several instances of an anonymous struct within an anonymous union within a class. Stewart.
