With Const,

dataProcessor( cast( const )( importantData[5 .. 14] ) );
Don't cast to const/immutable unless you have a good reason to
do it, and you know what you are doing (and most times you
don't know it).
More generally, minimize the number of cast() in your D
programs. You can use a search to count how many "cast(" there
are in your whole D codebase, and you can try to reduce that
number.

I am trying to avoid it as much as I can, though this "shared"
keyword is not leaving me alone. Most of the projects I am
working on use multiple threads, and I am mostly obliged to use
casting many times. I am getting worried some times about what
the compiler is doing when I do casting other than just changing
a simple understanding like taking the first byte of ulong when I
do casting, etc. Please do not suggesting to use __gshared. It is
ugly looking.
