Hello,

Consider an 'empty' struct as follows:

struct Test {}

When printing it's size, it's always 1.
void main()
{
writeln(Test.sizeof);

Output:
1

Why is it not 0?  What about struct Test is consuming 1 byte of 
memory?


Thanks,

C++ exhibits the same behaviour for what is most likely the same 
reason: so that empty structs can be allocated without two 
distinct objects having the same memory address (
