Returns aProc object that takes arguments andyields them.

This method is implemented so that aYielderobject can be directly passed to another method as a block argument.

enum =Enumerator.new {|y|Dir.glob("*.rb") {|file|File.open(file) {|f|f.each_line(&y) }  }}

                static VALUEyielder_to_proc(VALUE obj){    VALUE method = rb_obj_method(obj, sym_yield);    return rb_funcall(method, idTo_proc, 0);}
