Smarter casting of similar types

[elliotchance]

For example trying to pass in an int to an int64 results in a panic. It should handle any casting that the compiler would normally handle.

Can you please say what do you mean, and maybe i can help with this one.

[elliotchance]

Add := tf.Function(t, func (a, b int64) int64 {
    return a + b
})

Add(3, 4).Returns(7) // fails because int(3) isn't compatible with int64(3), etc

If the compiler knew the destination type it would handle most of these castings automation.

@elliotchance i will jump on this.
