I was trying to implement unary * (list flatten or "splat" operator) in pugs yesterday, and I came to the conclusion that I really don't grok how context works in Perl6 (I also really don't grok Haskell, but this is another story...).
if I understand correctly, all these are equivalents:
my @a = 1,2,3; my @a = (1,2,3); my @a = list 1,2,3; my @a = [1,2,3]; # or does it make @a[0] = (1,2,3)?
and all these are too (they make $a a reference to an array):
my $a = 1,2,3; my $a = (1,2,3); my $a = list 1,2,3; my $a = [1,2,3];
I'm not sure what the following do (assign 1 to $a maybe?):
my $a = [EMAIL PROTECTED]; my $a = *(1,2,3); # or is this a syntax error? my $a = *(list 1,2,3); my $a = *[1,2,3];
and I have absolutely no clue about the following:
my *$a = @a; my *$a = [EMAIL PROTECTED]; my *$a = (1,2,3); my *$a = [1,2,3];
thanks for any help.
cheers, Aldo
