Absolutely right. You explained it better than I could.
Now, if I might give a historical note about this discussion...keep in mind that what follows is purely historical and is not even close to the current language...
Actually English used to use "to be" as well as "to have" to form the past in the same way as French...the most famous example is the Christmas carol "Joy to the world, the Lord
is come." Not "has come"..."is come." This text was written in 1719. There are some other examples in the King James Bible (1611) which is a good source for Early Modern English...
And he answered and said, Babylon
is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground. (Isaiah 21:9b)
The stone which the builders refused
is become the head stone of the corner. (Psalm 118:2)
And she said, The glory
is departed from Israel: for the ark of God is taken. (1 Samuel 4:22)
For death
is come up into our windows, and
is entered into our palaces, to cut off the children from without, and the young men from the streets. (Jeremiah 9:21)
Hope you found that interesting!
