in reply to Will my code work in Perl 6?

Perl 5
while <STDIN> { ...

In Perl 5, the parens are not optional. And please use a monospaced font for code :).

dot/underscore
String Concatenation from . to _. Note: whitespace is neccessary.

Only if there's a \w character next to it. $foo{bar}_$foo{bar} will be possible, but $foo_$bar will not (or at least not DWIM).

'for' is now a shortcut for 'foreach'.

I don't know if shortcut is the right word, but currently, for and foreach are exactly the same. That is, foreach (EXPR;EXPR;EXPR) and for (LIST) work.

    Hi, thanks for the corrections.

    And please use a monospaced font for code :)

    I thought I was! It looks ok on my screen. But my fonts were a little messed up by Opera. I checked it a few days ago in IE and it looked ok too.

    I was confused about the for/foreach bit. Apocalypse 4 says: 'And for will now always mean "foreach"'. Now I'm more confused. perlsyn says: '"foreach" keyword is actually a synonym for the "for" keyword'. I suppose it means that neither for, nor foreach will have the C-style (;;) construct.

    Thanks for the help.

      It seems Konqueror renders <pre> in whatever font the underlying element has. I don't know if that's how CSS was supposed to work, but you could of course add PRE { font-family: courier; } to your style sheet.

        Right. the <tt> is usually rendered as monospaced font. But it is useragent-dependent. Stylesheets are preferred.

        Thanks again --Simon
