Here you're passing a single argument to say, the array @x, which is
stringified by calling the gist method on it. It's the same as if if
you had said:
say @x.gist;
[1] > say |@x
abcd
Here you're passing four arguments to say, the elements of @x. It's the
same as if you had said:
say 'a', 'b', 'c', 'd';
I ask because I want to know its effect is on
my $proc = run(|@x, :err, :out)
run takes a slurpy list of arguments, as indicated by the *@args
parameter in its documentation <https://docs.raku.org/routine/run>, so
it doesn't matter if you explicitly flatten @x with a pipe. It'll work
the same either way.
I guess I am asking what the flattening does.
Why is this proper
my $proc = run(@x, :err, :out)
and this is not
my $proc = run(@x, :err, :out)
