I want to echo the comments of Wiz Zumwalt in The Wizardry Consulted: "Sure, if you've got a computer that can render hieroglyphics, and if you never need to remember what you did."
On the other hand, Wiz later used a line of APL to stump a dragon in the riddle game. So there's that.
(Wiz's coworker Jerry was exploring the use of APL as a language for their magic spell compiler, originally written in a Forth-like language.)

While a common sentiment, it has about as much merit as saying: "look at those japanese characters. You can't read them, therefore japanese is a terrible thing".
