`new`

[71104]

Provided as a global utility function (it will not become a keyword, it can be overridden by defining variables and parameters with the same name).

The use case is creating instances of objects provided by the native environment, e.g.:

new Error "something went wrong"

Or:

new Date 1440342320000

Note that associativity is left-most, i.e.:

(new Date) 1440342320000

The number of arguments that still need to be applied before returning the new instance is determined by the length of the constructor.

[71104]

After 7bf9613 all the global constructors have this as the first parameter, so this is no longer an option. new should be implemented before the next release. I'm also marking this a bug.

[71104]

Based on the new unmarshalling algorithm for native closures, the number of parameters to apply is no longer determined from the length of the native closure.

For native constructors new should work like this:

new Date {1440342320000}

Note that this is not specified because it's bound by new. A global non-constructor function would still need an explicit this:

alert window {'hello'}

e9392f8 introduces new, but only for Lambda closures.
