I updated my Perl 6 slides and Masak commented on a lot of my slides. Thank You!
For example for writing to a file I had the following: #!/usr/bin/perl6 use v6; my $filename = "temp.txt"; my $fh = open $filename, :w; $fh.say("hello world"); Masak: > I'd recommend $fh.close; it's more important than in Perl 5 because of the new GC. Which brings up a question: Can I rely in Perl 6 that a file is flushed and closed correctly when Perl shuts down? The probably more interesting case is this: #!/usr/bin/perl6 use v6; my $filename = "temp.txt"; { my $fh = open $filename, :w; $fh.say("hello world"); } { my $in = open $filename; say $in.lines } Can I be sure that the file is already flushed and closed when $fh goes out of scope or do I need to explicitly call $fh.close in the first block?
