The inout inside the delegate is wrapped just like the inout of
the 'this' parameter. effectively, this becomes equivalent to
several function signatures:
int opApply(scope int delegate(ref T value) dg)
int opApply(scope int delegate(ref const T value) dg) const
int opApply(scope int delegate(ref immutable T value) dg)
immutable
int opApply(scope int delegate(ref inout T value) dg) inout
AFAIK, there was a bugzilla issue for it. Wasn't it implemented?
