I also would like to have Call by Reference, but the lack of it doesn't
mean, that "Euphoria is rather useless for programming real applications".

Because of the lack of Block Comments, "Euphoria is rather useless for
programming real applications"??? Maybe you should look for a good
editor, that can handle line comments comfortable.

Maybe this wouldn't be necessary theoretically, I don't know.
But where is the problem using it?

Is there an unwritten law, that case sensitivity isn't good for
programming newbies?

Case sensitivity increases the number of possibilities we have, for
creating names of routines, constants and variables. I like that.

Sorry, but nothing that you wrote, is an argument, why "Euphoria is
rather useless for programming real applications".
