Not quite. -noboundscheck turns off _all_ array bounds checking, whereas -
release turns it off in @system and @trusted functions, but not in @safe 
functions. But unless you've marked your code with @safe or it uses templated 
functions which get inferred as @safe, all of your functions are going to be 
@system functions anyway, in which case, it makes no difference.
