Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/range-v3) and found it was in an excellent condition.

@conda-forge/help-c-cpp this should now be ready for review.

range-v3 is a header-only C++ library implementing the C++20 ranges proposal for earlier versions of the language (C++14 and C++17). It has no dependencies apart from the standard library.

See also #7824 .

@conda-forge/help-c-cpp could I get a review please?

[bluescarni]

@apmorton @isuruf thanks for the review, I have addressed the comments.

@isuruf @apmorton do you think this is ready to be merged?

[apmorton]

LGTM, but I'm not a maintainer here - just another user interested in having range-v3 on conda-forge.

@isuruf any idea why the build with NMake is now failing in Windows?
