Exegesis 3 Released (Perl 6 Examples)

chromatic writes "On the heels of Larry's most recent revelation, the mad scientist of Perl (Damian Conway) has followed up with Exegesis 3. His article gives working Perl 6 code examples of Larry's design decisions." Lots of good stuff in here.

Some thoughts

[reynaert]

Some of this new stuff seems to be seriously blurring the difference between language and library.

Of course it's cool to write something like @costs, but why must be an operator? It seems to me it would work just as well as an ordinary procedure.

I'm wondering if they are thinking about constructs to define new syntax at runtime. In Scheme for example most of the syntactic forms are defined in the library using define-syntax .

Bingo. Perl has very malleable syntax, which is perhaps not as flexible as, say, SML, but still has had a philosophy of letting you rewrite good chunks of perl in perl. Perl6 is just adding to the potential confusion, letting you write code as twisted and evil as you want to. Besides, if you tend to write mathematical apps commonly ... well, you might not write them in perl, but you probably do at least " on an easy key (I had to copy and paste it myself). " does not need to be an operator. It just can be.
