Be wary of functions which take several parameters of the same type

a way to avoid this in python that i quite like is to require keyword arguments:

  def foo(*, x, y):
      pass
  
  # you must do this
  foo(x=5, y=6)

  # you cannot do this
  foo(5,6)

  # and therefore you also may not
  foo(6,5)

This is a little autocratic but the other nice thing is that if you’re finding it really painful to use it means you should probably refactor anyway.

I prefer to let the IDE do this.

Developing C# in rider if you call `foo(a,b)` then it'll display as `foo(from: a, to: b)` in the IDE.

All Jetbrains IDE do this (AFAIK). One can even configure the cases when these are displayed (ie. only show the hints when there is an ambiguity)

for my own uses, that's great.

I write my libraries like this because i want to beat my users into being explicit -- thus the "a little autocratic, but.." caveat.
