This used to compile (probably dmd 2.060):
struct Foo {
immutable int y;
void bar(TF)(TF f) pure {
f(1);
}
void spam() pure {
bar((int x) => y);
}
}
void main() {}
But now it gives:
test.d(4): Error: pure function 'test.Foo.bar!(immutable(int)

My guess is that before 2.063 immutable int y was implicitly
static, but now it is per instance data which requires context
pointer which is deduced to be impure - that why compilation
fails (try placing static attribute). In other words, before
2.063 this was a function and now

Yet, in the code I used to initialize y in the normal constructor
of Foo. If now I tag y as static, that's not possible any more
(Error: can only initialize static const member scale inside
static constructor)

The reason it worked in normal constructor prior the change was
probably the same bug.
