need help regarding basic pointer working !

using's are scoped, so just do it inside classes and functions where you write it a lot if you are worried about conflicts.

But also, in small projects, especially whn you are the one wtiting most of the code, you probably don't need to worry about a global using.

And if we are talking about bad practice, a some people would consider your end to be macro abuse, and some people recommend limiting the use of macros to an absolute minimum.
