Require sequence compile error

It seems the require order is not quite the same. I needed to make the following change in order to get to compiling:

```diff
+require "./pages/main_layout"
 require "./pages/**
```

Else I was getting an 
```shell
Error in src/pages/blog/archive.cr:1: undefined constant MainLayout

class Blog::ArchivePage < MainLayout
```

I have no idea how to debug this, any tips?
