Oops, forgot to change the bottom line: [=, $var1, $var2]() [&, $var1, $var2]() The first line means "bind any implicit usages of variables by value, and also bind $var1 and $var2 by value". The second line means "bind any implicit usages of variables by reference, and bind $var1 and $var2 by value". This exists in C++ but C++ allows you to drop the leading = or &. We cannot, for precisely the reason you mentioned.
