--- Comment #1 from ensadc at mailnesia dot com ---
The diagnostic is required by the standard.

[expr.prim.lambda.capture]/2
(http://wg21.link/expr.prim.lambda.capture#2.sentence-2):

If a lambda-capture includes a capture-default that is =, each simple-capture
of that lambda-capture shall be of the form “& identifier”, “this”, or “*
this”.
