(::Proc::_Callable g) -> ::Proc

meth >> g → a_proc

static VALUE
rb_method_compose_to_right(VALUE self, VALUE g)
{
    g = to_callable(g);
    self = method_to_proc(self);
    return proc_compose_to_right(self, g);
}

Returns a proc that is the composition of this method and the given g. The returned proc takes a variable number of arguments, calls this method with them then calls g with the result.

Example

def f(x)
  x * x
end

f = self.method(:f)
g = proc {|x| x + x }
p (f >> g).call(2) #=> 8
