I think you're just afraid of lambda ;-0 Here's my proposal: (defun url-fetch (url &optional silent callback) "Fetch URL into current buffer. If CALLBACK is nil, do it synchronously and return a status flag." But I also like the idea of passing url-request-method and such as explicit arguments. And I'm not sure what it should return if CALLBACK is non-nil (both in the case where the request is performed asynchronously and when it's performed synchronously). Stefan
