RubyKoans: broken koan?

ruby

Solution

Oh, I tested this koan. The error is on line 21 if you noticed that, not the "test_calling_global_methods_without_parentheses" method. It's the "test_sometimes_missing_parentheses_are_ambiguous" method goes wrong as it should be. You are expected to correct that method.

def test_calling_global_methods_without_parentheses
  result = my_global_method 2, 3
  assert_equal 5, result           # You're fine with this koan.
end

# (NOTE: We are Using eval below because the example code is
# considered to be syntactically invalid).                  
def test_sometimes_missing_parentheses_are_ambiguous
  eval "assert_equal 5, my_global_method 2, 3" # ENABLE CHECK
  # **LOOK HERE~~~ HERE IS THE ERROR YOU SEE** Just correct it.

And if there is any koan you don't know how to deal with, just comment it.

Problem

Probably a sign of an amateur that I'm wondering if the problem's the koan (rather than me), however, consider this koan ``` def test_calling_global_methods_without_parentheses result = my_global_method 2, 3 assert_equal __, result end ``` Note, my_global method is ``` def my_global_method(a,b) a + b end ``` This is the hint it gives me in the terminal ``` The answers you seek... <"FILL ME IN"> expected but was <5>. ``` So I did ``` def test_calling_global_methods_without_parentheses result = my_global_method 2, 3 assert_equal 5, result end ``` and I got this error ``` Users/mm/Sites/koans/about_methods.rb:21:in `eval': (eval):1: syntax error, unexpected tINTEGER, expecting keyword_do or '{' or '(' (SyntaxError) assert_equal 5, my_global_method 2, 3 ^ from /Users/mm/Sites/koans/about_methods.rb:21:in `test_sometimes_missing_parentheses_are_ambiguous' from /Users/mm/Sites/koans/edgecase.rb:377:in `meditate' from /Users/mm/Sites/koans/edgecase.rb:449:in `block in walk' from /Users/mm/Sites/koans/edgecase.rb:460:in `block (3 levels) in each_step' from /Users/mm/Sites/koans/edgecase.rb:458:in `each' from /Users/mm/Sites/koans/edgecase.rb:458:in `block (2 levels) in each_step' from /Users/mm/Sites/koans/edgecase.rb:457:in `each' from /Users/mm/Sites/koans/edgecase.rb:457:in `each_with_index' from /Users/mm/Sites/koans/edgecase.rb:457:in `block in each_step' from /Users/mm/Sites/koans/edgecase.rb:455:in `catch' from /Users/mm/Sites/koans/edgecase.rb:455:in `each_step' from /Users/mm/Sites/koans/edgecase.rb:448:in `walk' from /Users/mm/Sites/koans/edgecase.rb:470:in `block in <top (required)>' ``` Does anyone know the problem or can you tell me how to skip a koan?
