Removing direct value access

[juxeii]

Hi,
I wonder what would be the fastest way on removing the error-prone * and -> operators for direct value access?
Towards a more monadic implementation I do not want the users accessing these public and unsafe operators.
Would it make sense to declare all the non-class templates as friends to the optional class?
I'm not an expert in library design and your implementation is way beyond my abilities...

Thx

Probably easiest to remove those functions from the source and run the tests to find any places they were called, then replacing those sites with direct accesses by making the non-members friend functions like you say.

For now I go with a subtype approach and see if I can delete the unsafe operations.
