Re: Perl 5 -> 6 do's and don'ts?

Probably the biggest thing in my mind is that you shouldn't rely on the current dynamic scoping behavior of $_ because it'll be lexically scoped in Perl 6. Anything that uses select is also highly suspect.

I presume you mean 2-arg select, or is 4-arg also going the way of the dodo?

We would already have deprecated 4-arg select if we had anything decent to replace it with. Filehandles aren't well represented by small integers in Perl. Indeed, some filehandles map to more than one file descriptor underneath. Filehandles (and all other event-producing entities) need to be tied together with a consistent event-handling model.
