Why think unit tests should be in their own source code hierarchy instead of side-by-side

I *love* built-in unittests. Putting them right after each 
function makes things so much easier.

Tests in their own file is something from 90-s. It's 2018 and I 
want to be able to write tests anywhere I want.

"They increase build times" - fix compiler, not my code.

"version(unittest) will cause you problems if you write 
libraries" - fix dub, not my code.

Built-in unittests are part of D's specification. As long as it 
allowes to do so, I'll carry on writing unittests in my code and 
nobody can take it from me.
