Re: Re: Re: Re: Re: Apocalypse 3

Excellent. I would have only assumed JIT tokenization was the course to be taken, after reading Larry's third Apocolypse. I'm looking forward to seeing some of your applications of these new ideas in your exegesis.

By the way, what is the purpose of a my sub? Is it just a way to have a "lexically scoped" function? That is, is it a way around the current my $func = sub { ... }; $func->(...); approach?

By the way, what is the purpose of a my sub? Is it just a way to have a "lexically scoped" function? Exactly. Although that "just" is a little unfair. Lexically scoped subs are a very significant addition to the language. For example, they allow user-defined operators to take effect only in a limited -- and compile-time determinable -- scope, thereby preventing widespread chaos and madness when some module you import decides to define a high-precedence `;#` operator and accidentally eats all your close-commented end-of-statements. `;-)`	[reply] [d/l] [select]

Exactly.
