in thread About the + in front of a hashref that disambiguates from a code block.

I wonder if unary-plus existed before this use came about.
I'm pretty sure unary plus has been around since perl 1.0.0. I seriously doubt that writing '+1' in perl 1.0.0 resulted in an error. In fact, I've a hard time thinking of a programming language that doesn't have unary plus.
