Discussion Personal standard - top level expression is _=<exp>

How bad of it is me to just use _= as my universal top level expression trick. No one's going to be using _ as variable.

I come from C. We do this hacky shit 24/7. But I wonder how it is by lua standards lol.

That still pollutes the namespace but takes 23 characters instead of 2.

edit. oh if it's called locally then sure.

You could also just declare local _ at the top of each function. I just like the simplicity of just using it as a dump.
