Hello,
I have a wish for Perl 6. I would like if the open-funktion
opens only a file if it doesn't exist.
Of course, I can first test if the file exist.
if (-e $filename)
{ print "file already exists!"; }
else
{ open (FH, ">$filename") }
My suggestion is to have a character for t

Hello,
I am missing, in Perl5, some shortcut for matching not whole word,
e.g.:
/^--v(?:e(?:r(?:s(?:i(?:on?)?)?)?)?)?$/
Would there be something in Perl6?
For Perl5 I suggest somenthing like this /--v(?-ersion)$/
Best regards
Hello,
I noticed recently a discusion about *printf*() function.
I wish to be able to specify formating of groups of parameters.
Eg.
printf("Date: %11{%d.%d. %4d}, City: %s\n", $day, $mounth, $year);
Variables $day and $mounth could be one or two digits. There should not

Well, I don't think there's an *exact* substitute for that maximally

I apologize in advance for posting yet another "suggestion" without having
full knowledge of all apocalypses, and I fear (for a very positive
meaning of "fear") that the answer will be: "but that is already

Well, the point is that I wonder wether Perl6 will support cartesian

So outer is somewhat like {} in shell globs?
perl -le'print for glob "{1,2,3},{4,5,6}"'

Is that on the resources page in the web or in the README?
Fixes welcome.

I did some research on GMP and LGPL, the results are attached. I don't know if
this is a go/nogo for GMP, but it is pretty clear now.
Further the FSF asks for perl6/parrot to use Artistic 2.0, what is the discussion
state on that? (RFC 346)

Well, open being much like IO::All::io would really make me happy.
That is:
my $fh = open 'foo.txt';
