If I want to indicate that I <b>think</b> a past situation actually happened, can I use "will have + past participle"?<br/><br/>For example:<br/><br/>As you <u>will/would have noticed</u>, he's got new glasses.<br/><br/>Most people <u>won't/wouldn't have seen</u> last night's lunar eclipse.<br/><br/>Is it Common?
