That initializer is useless, don't do that, just use the slice.
static immutable Foo[] getFooList() { //static method
returning an immutable slice
Actually, that's a static immutable *method* returning a mutable
slice. It is like you wrote:
immutable {
// bunch of methods here
}
so it is applying to this. To make it apply to the return, use
parens around it:
static immutable(Foo)[] getFooList() {}
or
static immutable(Foo[]) getFooList() {}
the former is a mutable array of immutable objects and the latter
is all immutable
