Proposal: struct and array literal syntax

[Chris Miller]

This is an old idea I had, and also applies to struct initializers which  
now has ambiguity with literal delegates.

Given the following struct:
    struct MyStruct { int foo; int bar; }
can be created with the following proposed syntax:
    MyStruct!{3, 4}
which can be used in initializers and anywhere else MyStruct is expected.

For array initializers, see the following proposed syntax:
    int[]![6, 7, 8, 9]
which creates a dynamic array of 4 int elements.
This as well can be used in initializers and anywhere else such an array  
is expected.
