Backtick expressions (now) use the same scoping and same binding rules as other functions.

What do you mean by "now"?? There are no backtick expressions in Python anymore and they were never functions.
The only difference is that
class Class:
  stacticmethod = `...`
  staticmethod = lambda: ...
  def instancemethod = `...` # an instancemethod that's called with self passed in
  def property = property(`...`) # an instancemethod that's called with self passed in

You seem to be inventing new syntax as you go. And you haven't told us how the first two above differ.

That is what `lambda bar: foo + ^bar` means.

I have no idea what this means. You're giving syntax without semantics. The word "that" in your sentence is an unbound reference.

A caret in a backtick expression indicates that the name after the caret is a parameter. All names with the same name must have a caret before them. Mandatory parameters can be passed in as keyword arguments or as positional ones.

In a word, ick. So to find the parameters for a function, I need to scan through the entire text of the function looking for ^? And you think that's an improvement?

You've given no explanation of how this is better and saving typing the word lambda isn't enough. All in all this sounds like "but these go to 11" justification and that really is insufficient.

I'm -11.
