You usually should go with the symlinks for a normal usage. There're marginal use cases where you mount a folder, like modifying permissions, attributes, with not straight to learn tools like bindfs.
You mount a filesystem (container), whereas a folder is something contained in a filesystem (IOW, not a filesystem)
If you want/like/enjoy something, do it, don’t listen to others. It’s also OK to learn something but never use it, either for the joy of learning or learning new things and new ways of looking at things.
Perl was my first favorite programming language, I really liked it. my brain could connect with it easily(same thing wasn’t true for other PLs). It even helped me understand other programming languages better.
Pretty much this ^
Besides that, I still miss Perl, I loved it!
My current favorite language is Raku.
I was once also looking while Perl6 was evolving, and somehow liked it, but there was something keeping me out. There were no plans to allow me to use Perl6 the same way I (and everyone) uses Perl5:
$ binaryinterpreter script.pl
Maybe they'll will hear their users instead of ignoring (reasonable) requests (like a toolbar, or sorting status bar items) that are many years old and have thousands of stars.
I remember having to program a trap for double-clicking buttons in an application.
Then I had to implement a penalty for triple-clicking.
Later, I converted it to a progressive incremental penalty.
