Allow Recursive Functions to take extra function parameters for private fields

[awalterschulze]

For example

deriveEqual(T, T, func(A, A) bool, func(B, B) bool) bool

, where T contains a field with type A and B

This also includes:

• Compare
• Clone
• DeepCopy
• GoString
• Hash

This can be especially useful for time.Time, which has loads of private fields, but can be easily handled with a special case function.

Tackling a single one of these would be greatly appreciated.

The idea is when you traverse through the struct and find a field that matches the input type of one of the input functions, you should rather use the function provided in the parameter recursing deeper.
This almost the same as calling the Equal method rather than generating your own.

This is the generic version of issue #47

[OladapoAjala]

@awalterschulze is the generic version solved or it is still open?

[awalterschulze]

There is a lot of discussion about how to solve the generic version in #47
If you are interested, I don't think any work has been done yet

[OladapoAjala]

Nice, I'm interested in tackling the generic version, sounds fun to me!

[awalterschulze]

Go for it, first make sure you understand what has been agreed upon in #47
Do a small prototype, to make sure you don't do too much work before checking that we are on the same page.
