What is future of coding?

I feel it is not only language what could translate your ideas into reality.

Artificial intelligence in (future) editors (and also vim conceal) is
probably right way to enhance your coding power (with lambdas too).

If we like to enhance python syntax with Unicode characters then I
think it is good to see larger context. There is ocean of
possibilities how to make it. (probably good possibilities too). For
example Unicode could help to add new operators. But it also brings a
lot of questions (how to write Knuth's arrow on my editor?) and
difficulties (how to give possibilities to implement class functions
for this (*) new operators? How to make for example triple arrow

I propose to be prepared before opening Pandora's box. :)

(*) all of it? And it means probably all after future enhancement of
Unicode too?

Questions around "only one possibilities how to write it" could be
probably answered with this?
