agree for =>
but how many people use pascal eiffel etc? (go has a chance)
that's a reminder of an old, fading epoch, bland IDEs, hard-to-crunch fonts
BDL Guido once remarked in a pycon talk that today agencies would've charged you a high price to tell you what the word python might tickle in the subconscious of the common user, we should maybe write on what ":=" tickles in the mind of most programmers
The fact that := will be familiar to many people (especially if they
know Go, Pascal or Eiffel etc) is a point in its favour.
The => arrow puts the arguments around the "wrong" way compared to
name = expression
expression => name
Although personally I like that order, many people did not and I think
Guido ruled it out very early in the discussion.
Also it may be too easily confused with <= or >= or the -> syntax from
