I don't know, I'm fairly new to zsh myself. All I can say is that the
behavior of zsh feels more natural to me.

All languages? That seems exaggerated. How about this?

  int var;

How many languages will set `var` to null here? Is it all of them?

In the morally-equivalent shell code, bash does but zsh doesn't:

  typeset -i var
  echo $var

I don't know which of these languages conforms to the majority opinion
but neither can claim to do what *all* languages do.

FWIW, I rely on this behavior of zsh in my code (namely, that `typeset
-i var` sets `var` to 0).
