Tuples

[GoogleCodeExporter]

Currently I don't see any way to create anonymous tuples of types.

For example, in many other languages, (1, 'hello', 2.3) would create a tuple of 
type (int, String, double).

There are at least four components to this, to make it useful:

1) Ability to define tuple values: (1, 'hello', 2.3)
2) Ability to denote tuple types: (int, string, double)
3) Tuple assignment: (a, b, c) := (1, 'hello', 2.3);, equivalent to a := 1; b 
:= 'hello'; c := 2.3;. No tuple is actually created, it's just syntactic sugar.
4) Tuple unpacking: d := (1, 'hello', 2.3); (a, b, c) := d;, useful for 
unpacking tuples when returned from a function. This is for the case when a 
tuple is actually created as an object and needs unpacking.

I didn't check whether the above notation for tuples would cause ambiguities in 
crack. Another notation might be required.

The lack of tuples in their classical form is by design.

I've taken this opportunity to include this in the FeaturesCrackWontHave page:
