  • So if I want to find a “magic number” byte sequence in a binary file, how do I do that in Perl 6?

    • According to S32/IO [], the return type of slurp (which reads a whole file at once) is Str|Buf. A Buf is returned when a parameter :bin is passed to slurp. After that, you can treat the Buf you get as an array (because Buf does Positional, and do as advanced indexing operations as you need to find your byte sequence.

      I wish I could show this with real, working code, but Buf isn't implemented just yet in Rakudo.
