Hello Firsov,

The following quote from the Camel Book (4th Edition, 2012, Chapter 3: “Unary and Binary Operators,” Section “Terms and List Operators (Leftward),” page 98) may help:

In the absence of parentheses, the precedence of list operators such as print, sort, chmod is either very high or very low depending on whether you look at the left side or the right side of the operator. (That’s what the “Leftward” is doing in the title of this section.) For example, in: 
my @ary = (1, 3, sort 4, 2);
print @ary;         # prints 1324

the commas on the right of the sort are evaluated before the sort, but the commas on the left are evaluated after. In other words, a list operator tends to gobble up all the arguments that follow it, and then act like a simple term with regard to the preceding expression.

Hope that helps,
