For compatibility with prior revisions of C++,
a [*lambda-expression*](expr.prim.lambda.general#nt:lambda-expression "7.5.6.1 General [expr.prim.lambda.general]") with [*capture-default*](expr.prim.lambda.capture#nt:capture-default "7.5.6.3 Captures [expr.prim.lambda.capture]")= ([[expr.prim.lambda.capture]](expr.prim.lambda.capture "7.5.6.3 Captures")) may implicitly capture*this by reference[.](#1.sentence-1)

[*Example [1](#example-1)*: struct X {int x; void foo(int n) {auto f = [=]() { x = n; }; // deprecated: x means this->x, not a copy thereofauto g = [=, this]() { x = n; }; // recommended replacement}}; — *end example*]
