Yeah, infix doesn't go well with that. Even traditional mathematical notation ends up being ambiguous because of it. However, if all infix operators are given equal precedence, it all becomes very neat. See APL (https://apl.wiki) for an example of that.
At the same time Q (which is based on apl) only allows built in functions to be infix because otherwise your code gets unreadable Especially if you also have prefix notation.
in `one two three`, are one and two functions using prefix notation or is two an infix function that takes both one ant three as arguments?
It's not too bad if you have a small amount of infix functions to remember, but I don't want to second guess everything while reading code.
