Hi,
Still trying to find a way to have test code in my programs. Normally
not executed but an imported class could make some sense of it. Others
have tried already but I wanted to do the following which looks promising;
=begin Gnome-T
=begin code
my Int $i = 10;
=end code
=end Gnome-T
I c

FWIW, the same goes for:
dd Int.new; # 0
dd Num.new; # 0e0

Let me guess. The school prohibits object self-initialization? It has to be
done by external code?

Yes. I'm agnostic on this point, but there was a time when some
prominent Perl contributors were dogmatic about it and I didn't know how
widespread it was.

In general, the idea of initialized doesn't mean a lot in Raku, at least
not at the language level.
At any given time, any variable has a value. By default, if you've typed a
variable, it's initially set to the type itself (Any is the default type,
so the default default value). The only exception

Matthew has provided some concrete examples of default initializations. I'd
like to scratch the surface of more general problem: encapsulation. In many
cases only a class knows it's real internal structure and can use this
information to protect the data from misuse by 3rd party code which may
Hi Rob!
Thanks for the reply. So what you're saying is the "backslash-newline"
combination tells the REPL that it has received incomplete input? Otherwise
I don't see how the Raku REPL knows how to cycle from taking input at its
prompt and moving to the read/evaluate step.
I took a quick look at
