1.8.0-preview7 block-to-super bug/change or behaviour

[Kero van Gelder]

Hi!

Up to 1.8.0-preview6, the code below prints three lines (A, B, A).
1.8.0-preview7 prints only two (A, B).

What's going on?

Bye,
Kero.

class A
def initialize(&block)
p "A #{block}" if block_given?
end
end

class B < A
def initialize(&block)
super() { puts "world" }
p "B #{block}" if block_given?
end
end

B.new() { puts "hello" } # results in two lines printed, OK
B.new() # nothing printed

Seems [ruby-talk:77654] was wrong.

Yup, that's it.

Thanks!
