I didn't mean to necessairly use the syntax I shown, I agree it was
quite ugly ;). It was meant mostly to explain the problem in a clear
way. I was just wondering if there was a way to avoid this code

	if maxlength < 0:
		.. input(...)
		.. input(... maxlength=maxlength ...)	

But I might have found how to avoid the above by __calling__ the
internal object with maxlength=maxlength conditionally to maxlength >= 0
(very similar concept of ctx.tag(something=something), it shouldn't
clear the previous contents).
