Stylistic choices

I tend to prefer to use namespaces filled with constants, rather than using enums in most cases. For example using

namespace Element {
const uint8_t No_Element = 0;
const uint8_t Air = 1;
const uint8_t Water = 2;
const uint8_t Earth = 3;
const uint8_t Fire = 4;
};

instead of


enum Element {
No_Element, Air, Water, Earth, Fire
};

Is this bad practice?

You can make mistakes in the Elements::Fire or Attack_Damage::Fire
You can confuse, change them accidentally, or transfer some Fire properties.
when you use the #define you have more verbose, but more more reliable constants which cannot be accidentally refered to,changed  or substituted by something else without #undef or another #define.
