Perl Sigil is inherited from Shell Script Variable Expansion.
my $name = 'Kimoto';
my $message = "I'm $name";
I wish Perl's philosophy of respecting shell scripts became known.
This is not dirty things as some people say.

Perl's "sigils" are dereference operators , not true sigils ; BASIC had sigisl, PHP has sigils, Raku has sigils ... BASH and Perl 5 have dereference operators
if you think of them as dereference operators it is a lot easier to read Perl code
Partly yes, because
$$varin PHP reads: variable with name stored in$var, while in Perl reads: variable which$varrefers to.Partly no, because
$varand@varand%varare completely independent variables, and they likely shouldn't if they were dereferencing the same thing I guess.Also,
varitself is a bareword and does not exist as a variable without its sigil and outside of symbol table."$var and @var and %var are completely independent variables"
they're not independent in the symbol table
"
varitself" would be a subroutine, which is stored in the same symbol table and accessed by using the & "sigil" if you really want to use "&", though the compiler tries subs first when encountering barewordsPython is all of all unrelated in this entry.
Did you add the Python tag to this?
"read next" show me unrelated python topic.
If the Dev Community team knows this things, it may lead to improvements.
There is a "#python" tag on this post.
My question was, if you added the #python tag to this post, or someone else?
It's me, on the other hand, there is a reason to add it.
So you are misleading the algorithm by adding a Python tag to a post that has nothing to do with Python and then you are complaining that the algorithm does not work well.
Sounds totally reasonable.
To be honest, I don't feel this is the best way to do it. This would be a bit rough way.
On the other hand, I have felt algorithms that increase prejudice and prejudgment in many places.
I want to reduce these because some people are suffering from it.
This entry read next show pyenv. why?
I guess the read next entries are based on your own interest on the platform. They are different for me.
By the way, they don't reflect my interests that much either.
thank you.
I send a message and wait for improvement.
It feels like an algorithm that further widens the gap.
