Could you send same implementation to NyanRus/Noraneko ?

[surapunoyousei]

Almost code are good! Use Class provides us more clear code base.

Could you send same implementation to NyanRus/Noraneko ?

Ok I will set it to Noraneko. Could you check if the changes I made are correct? I'll open a PR in Noraneko after the review here.

おｋ

I suggest to use namespace
if you don't need to initialize, the namespace is better than class with static

[TheChilledBuffalo]

@nyanrus Thank you for the recommendation! Namespaces are actually better than using class here. I have committed the changes. Could you check if the changes are good?

[nyanrus]
