#arity_full?(cursize) ⇒ Boolean

we can have parenthesis with one expression inside everywhere only in FuncTree this is redefined for the function’s arity Note: if you change this method, please also update arity_full_monkey?

see below

Returns:

  • (Boolean)

def arity_full?(cursize)
  cursize >= 1
end

#arity_full_monkey?(cursize) ⇒ Boolean

this is for testing only. see 99_threadsafe_tc.rb there we will monkey patch arity_full? by adding some sleeping to easily slow down a given test-thread (while the other one runs normaly)

The rule is to keep this method here exactly same as the original

"productive" one

With this trick we can test threadsafeness without touching “productive” code

Returns:

  • (Boolean)
