I've made a lazy linq-like library for javascript in the past..

The problem i had was that the native array methods are rather fast while function calls (for moveNext) are quite slow, so i couldn't get a whole lot of speed out of it.

Newer javascript engines might be sufficient to offset that though.

I tried to get around this by creating overloads of almost all methods when you are operating on an array. `each` for instance, has a standard implementation using moveNext, and then an array implementation using a fast for loop. In some cases you could even drop down to native function calls.

Sounds reasonable. Could be better timing now as well, what with server-side javascript having become popular. Good luck with the library!
