Either the def of `local` is wrong, Or the current julia behavior is unexpected

@goerz

But seriously: does this cause any problems whatsoever with how you reason about Julia code?

Yes, seriously.

Until here I still don’t know what is the essential effect by writing local x. Because of people’s inaccurate wording.

I don’t know if local x means:

• introduce a new name x, which is required to be a local name in the current scope

or

• We might have owned a name x in the current scope already, and now we declare it to be local.

@Benny

and the wider Scope of Variables page in the Manual makes it pretty clear that

1. local statements introduce a local variable to a particular scope level in contrast with outer local variables of the same name.

Your wording is still confusing.

You can look up an English dictionary to find the meaning of introduce:

to mention something for the first time in a piece of writing

The first time here is essentially the same as

@WalterMadelim

help?> local
  local introduces a _new_ local variable.
