Mathematicians have an implied operator between symbols.  You can't do
that with multi character names.  Not in a way that can make sense, to
me.

Operator overloading, if done incorrectly, is a maintenance nightmare so
I don't think there will ever be a language with user defined implied
operators.

  %let * be the implied operator

Then one could write

  K = a b + c^2 a k;

which would mean

  K = a * b + c^2 * a * k;

where ^ is "to the power of" and +, * the usual mathematical operators.

And while I find it easier to read the former, I doubt it'll be
universally recieved since slightly later in the program one might
encounter

  %let ^ be the implied operator

  L = c 2;

and L is suddenly c squared.

Maybe I'll try a toy language with implied operators one day.
