Subject: [ruby-core:75498] [Ruby trunk Bug#12376] No error for elseif	condition

Issue #12376 has been updated by Yusuke Endoh.


You may want to use a code lint tool, such as [rubocop](https://github.com/bbatsov/rubocop).

BTW, next quiz:

~~~
> a = 1
> if a == 2
>   puts 2;
> elsif a == 3
>   puts 3.
> elsif a == 1
>   puts 1;
> else
>   puts 0;
> end
0
 => nil
~~~

Bug #12376: No error for elseif condition

Something I have been for a long time wondering about.
I don't know if this is a parsing problem or not but for me it seems like it is.

Replication:

``` ruby
$ irb
> RUBY_VERSION
 => '2.3.0'
> a = 1
> if a == 2
>   puts 2
> elsif a == 3
>   puts 3
> elseif a == 1
>   puts 1
> else
>   puts 0
> end
0
 => nil
```

Shouldn't we have a parse error triggered here? 
We can replace *elseif* for any other instruction like *foo* for instance.

I believe this behaviour is around for a long time.
