And this means the parser has to figure out whether you mean dot for attribute access or dot for concatenation. That's not exactly a _hard_ problem, but it's not _trivial_.
If you say it mis not hard for the parser, ok - but it seems impossible for humans:
upper = " World" print ("Hello". upper)
That's attribute access.
But you are suggesting it should be string concatenation. It is already in use for attribute access, as you can see - and one writting a program, or reading one should not have to be thinking """ah - but here I can't use the "." because I am concatenating a string in a variable, not a literal string""""
The suggestion was to use it in place of implicit string concatenation, which occurs only between string _literals_:
print ("Hello" . " World")
and is currently illegal ("SyntaxError: invalid syntax").
What is that? One thing that works in a way for literals and in another way for expressions? Sorry, but there is onlye one word for this: Insanity!
