Re: [boost] [outcome] Whether to default EC = error_code for result?

Maybe, as others observed, you should call it -- those codes are not necessarily errors.

Already ahead of you on that.

So, are you saying you want `EC` with no default in `result` and `EC` to default to `std::error_code` in `outcome`? [snip] If what you are saying is true, that all non-trivial usage will be to compose one's own type, then you could provide `basic_result` to be used for building custom types: no defaults. Next, in another header you could provide an alias:

``` template <typename T> using result = basic_result; ``` Similarly to what you do for `unchecked` and `checked`.

Yes that could work. So we'd gain a non-defaulted `basic_result` and `basic_outcome` with typedefs to defaulted `result` and `outcome`. Nice.
