The C++ standard for the F-35 Fighter Jet [video]

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.
