On run.dlang.io:

```
onlineapp.d(1): Error: unable to read module `console`
onlineapp.d(1):        Expected 'sidero/base/console.d' or 
'sidero/base/console/package.d' in one of the following import 
paths:
import path[0] = /dlang/dmd/linux/bin64/../../src/phobos
import path[1] = /dlang/dmd/linux/bin64/../../src/druntime/import
```

Searching on code.dlang.org: Found 0 packages. So not much of a 
replacement.
