I've impl'd Drop for a cached data type T to give an error if you are dropping T with its dirty bit set.
Unfortunately, if the code panic's, drop(T) will get called and then I have a bunch of spurious "dropping while dirty messages" even though in this exceptional case I don't want to do the check.
Is there anything built-in to panic that I can check to see if the current thread is in a panic state?
I know I can write my own macro to do this, but wanted to check if there's a better way.
Also, panic!() in drop does not respect the RUST_BACKTRACE env variable and prints backtrace puke no matter the value of RUST_BACKTRACE.
