Change Description

These const qualifiers were unused, triggering GCC warnings when compiling with -Wextra.

[LeStarch]

I think this will come back to us, but if it fixes issues today then we can merge it.

[Joshua-Anderson]

This fixes warnings preventing us from enabling -Wextra. Let's merge it for now, adding it back in later if we add const to those functions should be easy (and the compiler will warn us).
