a = a; // misra

Actual code i have seen with my own eyes. (Not in F-35 code)

Its a way to avoid removing an unused parameter from a method. Unused parameters are disallowed, but this is fine?

I am sceptical that these coding standards make for good code!

Especially since there is a widely recognized way to ignore a parameter:

    (void) a;
Every C programmer beyond weaning knows that.

I'm sure thats disallowed for the C-style cast.

Fwiw, unused-cast-to-void is a case that GCC and Clang ignore when using -Wno-old-style-cast, which is what most projects prohibiting C-style casts are going to be using (or whatever the equivalent their compiler provides).
