Is it possible in C# to overload a generic cast operator in the following way?

Just wondering if there is anyway to represent the following code in C# 3.5:

public struct Foo {

    public Foo(T item) {
        this.Item = item;

    Conversion operators can't be generic. From the spec section 10.10, here's the format of a conversion-operator-declarator:

    conversion-operator-declarator:
        implicit   operator   type   (   type   identifier   )
        explicit   operator   type   (   type   identifier   )

    Compare this with, say, a method-header:

    method-header: attributesopt method-modifiersopt partialopt return-type member-name type-parameter-listopt ( formal-parameter-listopt ) type-parameter-constraints-clausesopt

    (Sorry about the formatting - not sure how to do it better.)

    Note that the operator format doesn't include a type parameter list or type parameter constraints.
