Re: string to integer?

dd is a function that outputs a value, and dd returns Nil. You're assigning the result of dd to $x, which resets the variable to its default value, which is the (Str) you see, i.e. an undefined String. Just throw out the dd, you don't need it to stringify things, only the ~ or + prefix is

Re: Why use dd to convert a string to an integer?

Moarvm is the Perl6 Virtual Machine that is one of the targets Rakudo compiles to (the JVM is another). Basically at the moment when people talk about Perl6 that mostly mean Perl6 compiled with Rakudo running on MoarVM. (As I understand it). the dd bit was not in the example as part of string
