Bug 24650 – foreach should support inout for callback delegate

struct S { int opApply(int delegate(inout(int)) dg) { dg(1); return 0; } int opApply(int delegate(size_t, inout(int)) dg) { dg(0, 1); return 0; } } void main() { import std.stdio; S s; foreach(n; s) // error on this line writeln(n); } onlineapp.d(21): Error: variable `onlineapp.main.__foreachbody2.n` - `inout` variables can only be declared inside `inout` functions
