But as was noted earlier - the OP's question concerned how hard RPG was to learn. Not whether it was easier to perform certain tasks. And it is easy to learn.

... I don't think so, there are some points, making it hard to learn:
- no reserved words
True - and there are very few in most modern languages so I don't really see the point.
- strange dialects, tolerated by the compiler (cycle programming, level breaks, MR ...)
I would never teach any of this to a new programmer. _If_ they end up in a shop that uses it they will pick it up - but I would never teach it from the outset so it is a moot point.
- complicated compile-bind
CRTBNDRPG with a binding directory. Really complicated. Name a _compiled_ language that is any easier. Having explored node.js and Python those to me are much harder to deal with until you understand the surrounding infrastructure. Why does that make RPG harder? Have and class paths and on and on.
- compiler creating programms, that could not run (weak type checking)
If you decide to lie to the compiler - the only way this will really happen - then all bets are off.
- storage description in datastructure (I call it binary huddle)
As compared with ? The only other language where I find it easer is PHP - but then I give up strict typing which you seem to think is essential.
- no "state of the art" IDE (RDI is just a joke, compared to Java - Eclipse or visual studio)
I've been using Visual Code a lot lately trying to convince myself it is worth the effort and it drives me nuts. RDi is Eclipse plus - so saying it is a joke compared with Eclipse makes no sense.
- strange datatypes (int with scale and precision)
I assume you mean the old binary (B) type. The only reason that even exists in RPG IV is for compatibility with previous versions of the language. Again something nobody would teach to newbies.
I could also come up with similar lists for just about any language but I won't bother because there are enough religious zealots out there who have already made such lists to prove that "their" language is "the" language.
I think it was Brad who said that he uses a mixture of languages using each for its strengths. I agree 100% and I know Scott K is in that camp.
This was about ease of learning and having taught RPG to a LOT of people I think I'm qualified to say that it is indeed easy to learn the _modern_ (or current if you find "modern" hard to swallow) version.
And that is me done with this topic because, like anything of this ilk, it is getting hijacked to the point where it bears no relationship to the OP's question.
