No, it's a Proc :-) A Proc object can either be a block crystallised 
into an object, or a lambda. It carries the semantics of either.

$ irb --simple-prompt
>> def foo(&blk); blk; end
=> nil
>> foo { puts "hello" }
=> #<Proc:0x00007fdbc6eceba0@(irb):2>

>> lambda { puts "hello" }
=> #<Proc:0x00007fdbc6ec4f10@(irb):3>

You probably don't want to concern yourself with the differences, but 
the gory details are here:
