thanks for the advice mr danger -- i checked out a CVS copy, and needed to twiddle the version number as well.

have to say, i'm excited... even by my first for loop - parallel iteration is cool! likewise with the hyper operators - just like an even more brief map {} LIST. um... not sure about _ for concatenation though... call me a heretic, but i'd prefer an overloaded '+' to concatenate strings and '*' to repeat strings (a la perl5 'x' operator)... more parametric polymorphism please...

print "hello perl6 world\n";

my int @list1 = ( 1 .. 10 );
my int @list2 = @list1 ^* 2;

my int $i = 0;
for @list1; @list2 -> $a; $b {
    print "list iteration " _ ++$i
        _ ": a is " _ $a
        _ "; b is " _ $b
        _ "\n";
}

this works! although the contents of @list2, once hyper-doubled, appear to be (ie they print as) floating point numbers. nevertheless, this is extremely exciting.

You are correct -- numeric hyper-operators always convert their operands to floating-point in the current implementation. This behavior is incorrect.

You're a heretic. :)

Personally, I *HATE* it when + is overloaded as string concatenation. It leads to too many bugs/verbosities where you need to tell the language "no, I wanted addition here", or "no, I wanted concatenation here", especially in a language like perl which is able to DWIM-convert strings to numbers and verse visa.

[John M. Dlugosz]

I agree that overloading + is bad in this particular language, because the values aren't typed.

But, Perl doesn't need an explicit concatenation operator at all! Just use interpolation, "$head$tail" works perfectly well. For expressions, it's possible in Perl5 and easy in Perl6.

So, just get rid of the thing (or boycott it).
