	incorrect code for things like:

	Expression<Func<int?, int?, int?>> e2 = (a, b) => a + b;
	e2.Compile ().Invoke (null, 3))

	This should return null, but returns something else.

	* Introduce LINQ_DBG env variable, which generates a linq file in
	/tmp;   It currently does not work as well as it should, as the
	Func<> parameters do not mwatch the generated method.
	Investigate.


2008-01-20  Miguel de Icaza  <[email protected]>

	Introduce support for Nullable arguments, no code is generated for
	these yet, its only tests + node creation behavior at this point.

	* Expression.cs (BinaryCoreCheck): Do not allow "int?" and "int"
	as operators, they must both be nullable.

	NullableTypes in the arguments are transformed into the underlying
	values when doing the method validation.

	implementation (probably misses a few cases).

2008-01-14  Miguel de Icaza  <[email protected]>

	* Expression.cs: Bring back the (most) of binary operators.  Added
	type checking as well and reorganized the source file by topic
	instead of alphabetical sorting.

	types.

2008-01-13  Jb Evain  <[email protected]>
