std::array doesn't have a default printer.

Hi.

For std::array comparison I get:
REQUIRE( {?} == {?} )
I believe you support this for other containers. Can you add this when/if you have the time?

@DenisYaroshevskiy This isn't currently supported for any container from the STL by doctest - Catch2 does that. I might provide a second header with extensions and provide stringification for the most common containers/STL Types (because the main header will never include any STL/whatever header - the reason doctest compiles so fast).

Also default printers for containers is tricky - what if the container has 1 million elements? Would you want a short list of indexes that vary or an entire dump? A one-size-fits-all solution does not exist. You might write your own printers for types.

A related issue is printing ENUM values which will also go into such an extension header - see this: #121

@onqtam Oh - I see.

You do rely on ADL though for looking up types <=> for std ones it's not nice to do so.
Can I specialize smth instead?

UPD: Oh - I see - namespace dockets template<> struct StringMaker<T> {

• How about for generic test? I don't know what your minimal language requirements, but if you do it based on having nested iterator type, you should be OK even for 98.
• What if 1 million? Good point. Well - dump all is a very decent default if you could override it.

C++11 is the requirement for doctest 2.x (no longer C++98).

I think this is how Catch2 detects ranges.

I might implement matchers at some point and in that case when comparing containers you would get automatically the index that points to the different elements - this would be very hard to do with the current stringification of the values.

But currently I'm focusing on finishing the XML reporter.
