Anything can be credited better for some metric and evaluation scale, and what is obvious to one can be surprising to someone else.

x+y is several step away from plus(x,y), one possible path to render this would be:

  x+y
  x + y
  + x y
  + x , y
  + ( x , y )
  + ( x , y )
  +(x,y)
  plus(x,y)

And there are plenty of other options. For example considering method call noted through middot notation:

  x·+(y)
  x·plus(y)
  x·plus y
  augend·plus(addend)
  augend·plus addend

And of course the tersest would be to allow user to define which operation is done on letter agglutination, so `xy` can be x×y or x+y depending on context. The closest things I aware being used in an actual programming language is terms like `2x` in Julia interpreted as "two times x". But I don’t think it allows to configure the tacit operation through agglutination, while it’s allowing to switch first index to be 0 or 1 which is really in the same spirit of configurability over convention.
