[ruby-core:72034] [Ruby trunk - Bug #11802] Hash.new and {} have different behaviour

Issue #11802 has been updated by Hans Mackowiak.


`p {}` is parsed as `p() { }`

you see it when you try:

~~~ruby
p { :key => "value"} #which does raise a Syntax Error
~~~

you need `()`

~~~ruby
p({ :key => "value"}) # => {:key=>"value"}
~~~

* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
It looks that {} is not recognized as a variable sometimes.

irb(main):001:0> p Hash.new
{}
=> {}
irb(main):002:0> p {}
=> nil

Similar in rspec test:

expect(subject.something).to eq {} # fails on not given argument for eq
expect(subject.something).to eq({}) # works
