Every now and then I learn something new about Perl that is so basic.
I had mentally tagged => as "quote LHS, and then act as comma"; your
comment prompted me to look up perlop, which said,

If the argument on the left is not a word, it is first
interpreted as an expression, and then the string value
of that is used.

It's always nice when I can learn something new about something I
thought I understood already.
