Issue ID: 19387
Summary: [dip1000] __fieldPostblit should be scope or deduce
scope qualifier
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: normal

Currently, the __fieldPostblit constructor is not scope, this cause bugs that
looks like:
scope variable __copytmpXXX assigned to non-scope parameter this calling
AType.__fieldPostblit.
For example:
------------
struct C
{
void* u;
this(this) scope @safe {}
}
struct S { C c; }
void foo(scope S s) @safe {}
void bar(scope S s) @safe { foo(s); }
------------
<source>(9): Error: scope variable `__copytmp2` assigned to non-scope parameter
`this` calling example.S.__fieldPostblit
Compiler returned: 1
