The D2 language specification does not fully define the conversation performed
by cast() operation,
http://d-programming-language.org/expression.html#CastExpression.
For example cast() between basic data types of different sizes and signess is
not described.
e.g:
int a;
byte b = cast(int)a;
Casting pointers to basic data types is also not described.
I think the specification should define when the value is truncated, sign
extended or copied bit-by-bit, etc.
Maybe a reference to relevant C language specification would solve this issue.
