I want to know if a variable has changed .init, but I don't

int a;
int b = 0;
pragma(msg, a.init); // 0
pragma(msg, b.init); // 0
// how can I see that b has "= 0"?
Strictly speaking this is an ill-posed question. Are talking
about testing at runtime whether some variable was changed
from init to some non-default value?
No, at compile-time. It's trivial to see if init is changed,
but I want to see if it's set even if it's to T.init.
I see. No, I don't think this feature is suitable for declarative
approach abuse ;)
Even if you manage to hack something, it is unlikely to be
reliable, I'd recommend to stick to UDA's until compiler exposes
that info.
