in reply to usage of '+' sign in say statement
In Re: Pick a single item from a sub's return list , shmem explained it as "to disambiguate the list-parens from function-call-parens". BrowserUK used it with print in Re: Pick a single item from a sub's return list "to avoid the intensely annoying: print (...) interpreted as function".
