Summary: Compiling certain nested structs with -inline causes
error "*** is a nested function and cannot be accessed
from ***"
Product: D

This regression was introduced with the 2.057 release.
I first hit the issue with code resembling the following:
---------------------------------------------------------
import std.stdio, std.algorithm;
void main() {
writeln(filter!"a != 'r'"("Merry Christmas!"));
}
--------------------------------------------------------
Compiling with -inline gives:
/src/phobos/std/algorithm.d(1120): Error: function
std.algorithm.filter!("a != 'r'").filter!(string).filter is a nested
function and cannot be accessed from formatValue
This reduced test case gives a clue as to what is going on:
---------------------------------------------------------
auto fun()
{
struct Result {
this(int u) {}
auto bar() {
return Result(0);
}
}
return Result();
}
void main() {
auto t = fun();
auto a = t.bar();
}
---------------------------------------------------------
Compiled with -inline:
t.d(7): Error: function t.fun is a nested function and cannot be
accessed from main
It seems what is happening is that bar is being inlined in main, but
dmd doesn't know where to get the new fun.Result's context pointer
from.
