In theory, since it's never been documented, I could flip the define in config-top.h and disable it by default. I thought about doing that for bash-5.2, but did not.It's never been documented, and you discourage its use, just because you don't like the syntax that you created?
I think it's very niche use for shell scripting and doesn't need to be a
supported part of the shell.
The upper and lowercase features were user requested. The business of
making them into a parameter expansion with the ability to specify the
modified characters was my invention, and I think it's overkill. That's
why I think the parameter transformations, which work on the entire
value, are a better fit for script use.
I added the case-toggling feature, but I think the tilde was a poor
choice (though the best available) and, again, the ability to specify
a pattern is overkill. I think a parameter transformation would have
been sufficient here, too, but these came before the transformation
operators.
