Subject: [ruby-talk:26050] call_myself

Hi all,

sometimes, methods call itself inside.
("Recursion"?")

--- the example we all know---
def fact(n)
   if n == 0
     1
   else
     n * fact(n-1)
   end
end
-------------------

Sometimes, this is not obvious, because there might me a lot of other code.

def some_method arg
   # many LOC
   # some_method mod_arg
end

Is there something that makes it clear that the method calls itself?

def fact(n)
   if n == 0
     1
   else
     n * call_myself(n-1)
   end
end

... (or equiv) would be great for understanding programs, especially for 
longer methods.

Tobi
