Hi All,
I can easily get away with this in Modula2, but
how can I do this with Raku?
I wish to create a single variable that can be
manipulated in two ways:
1) as a fixed length string (Str)
2) as a fixed length buffer (Buf)
I can think of ways to do this, but it would
require separate variable and conversions routines
back and forth.
Any words of Raku wisdom?
Many thanks,
-T

No really.
Maybe if I was to tell you what I am trying to do.
I am trying to do a bitwise XOR on each byte
against another Buf. Then I want it to act
like a string again.
I want the variable to act as both an array
of characters and a binary array of bytes.
Convert a string to a Buf: say "abc".encode.Buf; # Buf:0x<61 62 63>
Convert a Buf to a Str: say Buf.new(97,98,99).decode; # abc
Technically, I think the .encode is enough for what you want:
say "abc".encode.does(Blob); # True
I like it. Thank you!
