Nice article, however font on this site is too small to read, I have to zoom in :(

Do more people have this problem? For me, the font size is similar to, say, Github.

Interesting approach to speed up compilation without running into dmd's problems of template instance emission when compiling multiple modules to multiple objects.

Many people use noatime or relatime when mounting their filesystems, so access time isn't the best eviction strategy unless you touch the files.

I think LDC has the same problems (template instances are emitted in the first module not the one that needed the instantiation?). Knowing this, you may be able to set up a case where things break, but I think it would have to involve recompilation with a different set of sources than the first compile. E.g. `ldc2 -c a.d b.d c.d` first, then `ldc2 -c b.d c.d`, and then trying to link. Which probably doesn't work well without caching either... We should deprecate non-singleobj compiles.

I forgot to mention this in the article, thanks! I read that a file's last access timestamp  may also not be updated on Windows (default Windows 7 setting), so I already had LDC `touch` the cached file upon a cache hit. Added it as a footnote in the article.

Maybe it is a font type (it is light) this is how it looks on my display:

But on my android phone it is OK. So maybe I should bought some 2k or 4k monitor ;)

Definitely one of the best upgrades I ever did (4k monitor). Warning: there's no way back.

I thought that LDC did not have that problem, or there was a flag change the behavior.
