From reading [this thread](https://discourse.julialang.org/t/is-not-an-operator/20221/2), I conclude that some symbols are parsed as infix, but some aren’t, for example

```julia
julia> function ↑(x, y)
           return x - y + 3
       end
↑ (generic function with 1 method)

julia> 9 ↑ 2
10

julia> function f(x, y)
           return x - y + 3
       end
f (generic function with 1 method)

julia> 9 f 2
ERROR: syntax: extra token "f" after end of expression
Stacktrace:
 [1] top-level scope at REPL[10]:0

```

Julia parses `↑` as an infix, but not `f`.

I don’t know if it is possible to make Julia parse `f` as an infix.
