Thanks for putting BillKSmith's sentiment to more verbose form. For some reason, it seems more palatable when presented like this. In retrospect, I guess this particular feature of the language can indeed be confusing. I guess it not like this for me because in my mind changing value of parameters from within the sub is connected with transferring variables I want changed by reference. Thus, in my mind, the problem is non-existent (which in fact is incorrect position)...

I guess that some code can indeed be seen as kind of a dark magic to person who does not have perfect understanding of the language (which I don't posess). This node would probably be a perfect example of good written, concise, yet hard to read code: trim() magic, if it is not properly commented.

It is good to talk to smart people. Thanks for the enlightenment.

edit: but then, I guess that almost any language contains features that are confusing to outsider, so it does not speak of Perl quality. Take JavaScript as an example. It is perceived as modern and quality programming language... and then... https://feross.org/never-use-semicolons/ Now let us talk about confusion. My head is spinning.
