Consider the following definition of Foo and an accompanying
unittest:
[code]
struct Foo
{
@property int[int] aa() {return m_aa;}
@property ref int[int] aaRef() {return m_aa;}
int[int] m_aa;
}
unittest
{
Foo foo;
assert(5 !in foo.m_aa); // Sanity-check to start off
foo.aa[5] = 1; // Add an element with key 5
assert(5 !in foo.m_aa); // ...huh. 5 didn't make it in?
foo.aaRef[5] = 1; // Try again, using the ref variant
assert(5 in foo.m_aa); // Works!
}
[/code]
I was under the impression that associative arrays are reference
types; if I pass a non-ref "copy" of one, shouldn't insertions
still be reflected in the original? Am I dealing with a bug or a
misunderstanding on my part?
