although it's right in most cases, it's still implying that compiler is
able to understand the code behind `in` and `[key]`, as they aren't
built into the compiler, but rather coded in druntime. producing
warning on such code can create wrong impression about compiler code
analysing abilities.

this time i think that it's a work for a linter, 'cause there is
nothing wrong with the code, it's just a questionable style. so let
linter question it. ;-)
