There are many things that was part of Python 1 that was removed.

This is not a "meaning". `++` means nothing. Indeed

SyntaxError: invalid syntax

The fact I understood it it's because I'm a programmer with more than 10 years
of experience, mainly in Python. And I discovered this defect by acccident,
because I wanted to write `a += b` and instead I wrote `a ++ b`. And when
happened, I didn't realized why it didn't raised a SyntaxError or, at least, a
SyntaxWarning. I had to take some minutes to realize the problem.
So, in my "humble" opinion, it's *highly* unreadable and surprising.
