Proposal: Make certain internal LINQ extensions public

[lngr]

I'm currently writing a custom LINQ Parser as documented here.
The example IsBlue uses the MemberFor method to obtain a locator for the property:

    var locator = memberCollection.MemberFor(expression).TypedLocator;

However, MemberFor is a member of LinqInternalExtensions that is marked internal (as indicated by its name). It took me a while to figure out why this doesn´t work locally :-)

Would it make sense to make a number of the internal extensions method public? They are tremendously useful for writing custom LINQ parsers. In particular, I'm using MemberFor() to find the correct JsonPathSegment and ReduceToConstant() to obtain the arguments of the MethodCallExpression.

(For now, I've copied both methods to my own repo).
