import std.stdio;
void main()
{
auto names = [ "foo", "bar", "baz" ];
void delegate()[] dgs;
foreach (name; names)
{
dgs ~= () => writeln(name);
}
foreach (dg; dgs)
{
dg();
}
}
Expected output: foo
, bar
, baz
Actual output: baz
, baz
, baz

To have a way out for old behavior by capture reference,
from: dgs ~= () => writeln(name);
to: dgs ~= () => writeln(&name);
