I actually consider "" to be a semi-function. It is a function in that it returns the contents as a string. that is

$string="$anything"

$string will be of type String and $anything can be of any time. So, "" converts variables to strings, just like a function. But it doubles as a command that sends data to std out too.

so, it is a semi-function (the only one) in my user manual [Smile]
