--- Comment #4 from Boris Carvajal <boris2.9 at gmail.com> ---
Something as simple as this fails now:

foo!(mixin("1+1"))();

In this context the old behavior of parsing mixin as an expression should be
restored (it worked from 2.063 according to run.dlang.io).

Another bug needs to be open to allow the new "mixin type" here, if it's ever
possible.
