I often use z as a temp variable when i need something to compare to when creating new code but don’t want a separate window to the side or to experiment with something but don’t yet know what the result can or will be. I use z purely just because i know z is very very unlikely to have been used elsewhere, and if for some reason it has, then i just name it ‘zz’.
This is actually temporary by the way. It does not stay in my code. Once I’m done with it, i delete it.



Foreign? For some these languages are native. Foreign is relative.
(I’m just being pedantic, i understand that relatively to you - and me - this is foreign)
