 It can when you make for example an assignement

    a = 12 # ==> local variable

 when it's not an assignement, then ruby search if it exist a local
 variable with this name. If the local variable is not found (i.e. it has
 not seen a line where this variable was assigned) then it's a method call.

 With Rite, you'll have a warning for this

        /* method call without arguments */
#if 0
        /* Rite will warn this */
        rb_warn("ambiguous identifier; %s() or self.%s is better for method call",
                rb_id2name(id), rb_id2name(id));
#endif
