Metaprogramming - defining a function

[yuyichao]

@NaOH

you don’t want to use eval because it is global scope only, you can use a macro when you need something local.

This is defining a global function.

@NaOH

I disagree, this is better to debug and reason about, specially if you are still learning

It’s absolutely wrong to learn the wrong pattern. You can call the macro as function for debugging just fine.

@NaOH

it is a pattern indeed, seen in many places, and suggested by many (smart) people (that tought me it),

I know and I’m really sad to see that. It’s absolutely a bad idea to do it. I’ve seen many issue caused by it and
I recommand against it everytime I see it. I’m not saying that you invented it, but you still shouldn’t do it.

@NaOH

So you never ever do this function insede macro? How do you do it? I used to do only macros, until Total Verb and others told me it’s better to do it this way, now you say, we shouldn’t.

I didn’t say you shouldn’t call function in macros, that’s just code organization and when you have something large that’s useful and that’s totally fine. I said your use of esc is completely wrong though.
