With the caveat that 'aa' is a manifest constant, meaning that its
values will be placed everywhere 'aa' appears in code. So, the following
loop *creates* an associative array at avery iteration:
while (/* ... */) {
if (aa[s] == 5) { // <-- oops :(
// ...
}
}
I think initializing it in a 'shared static this()' (or 'static this()')
block is better:
immutable long[string] aa;
shared static this() {
aa = [
"foo": 5,
"bar": 10,
"baz": 2000
];
}
void main() {
assert(aa["foo"] == 5);
}
