Let us break down what you are more or less proposing...
foo `baz` bar
... is translated into ...
How is that any easier to read or understand than...
I don't believe it is easier to understand, and would claim that it is
more difficult to understand, especially to users who have seen
backticks being used for repr. The only people it could be more
undestandable to is those who have used Haskell and have seen such
operator use in the past. I dont know how many of those users there are,
but I don't believe that the confusion would be worth it.
If you want to call a method on an object, call the method. If you want
to call a function that does automatic method invocation, that is fine
too. But what you are offering is more or less arbitrary infix
operators, which I can't see as being anything more than confusing to
new and seasoned Python users alike.
