=begin
Since method (({def})) returns the symbol in 2.1, it opens the door for a decorator pattern in which the method def is the argument to a method.
This currently works, unless the method happens to call another method and pass it a (({do/end})) block.
However, using (({{}})) instead causes no syntax error.
Here is the code to reproduce:

 def foo(meth); end
 x = Object.new

 foo def bar(arg)
   x.tap { }     #=> (no problem here)
   x.tap do end  #=> syntax error, unexpected keyword_do_block, expecting keyword_end (SyntaxError)
 end
=end
