Oh, that’s… not confusing at all.

  Yeah, the fact that the same symbol is overloaded with two meanings for the one-arg and two-arg (infix) cases adds some overhead to reading APL code. The precedence rules are very simple and uniform in isolation, but personally I find that applying them to (mentally) parse a nontrivial line of code is one of the hardest parts of getting started with APL.
