[ruby-core:66008] [ruby-trunk - Bug #10456] kwargs and block without comma should probably be a syntax error
From:
jacknagel@...
Date:
2014-10-29 23:01:57 UTC
List:
ruby-core #66008
Issue #10456 has been updated by Jack Nagel.
```ruby
def wat(something: nil &block)
end
```
`nil &block` is a legal expression (calling the `&` method on `nil` with `block` as the argument).
The expression is evaluated at method call time, not method definition time, so that's where the (correct) error shows up.

Bug #10456: kwargs and block without comma should probably be a syntax error

----------------------------------------
<pre>ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]</pre>
I experienced something very weird, when you define a method like this:
<pre>
def wat(something: nil &block)
end
</pre>
It actually doesn't come back as a syntax error
<pre>
Roberts-MacBook-Pro-2:~ robert$ cat test.rb; echo
def wat(name: "" &block)
end
Roberts-MacBook-Pro-2:~ robert$ ruby -c test.rb
Syntax OK
</pre>
Within the method, the block is never assigned either actually on method call:
<pre>
irb(main):007:0> def wat(something: nil &block)
irb(main):008:1> puts "Block: #{block}"
irb(main):009:1> end
=> :wat
irb(main):010:0> wat(something: 'hello') { "My block here" }
NameError: undefined local variable or method `block' for main:Object
from (irb):8:in `wat'
from (irb):10
from /Users/robert/.rbenv/versions/2.1.1/bin/irb:11:in `<main>'
</pre>
This behavior seems unlikely, it caught me off guard for sure.
