Thank you for your input, Adam. Real shame that there's no
built-in compiler solution and probably never will be according
to [1]. :(
D's competition got stuff like this right:
```
crystal build foo.cr
In foo.cr:6:6
6 | puts f.x
^
Error: read before assignment to local variable 'f'
```
[1] https://issues.dlang.org/show_bug.cgi?id=4595
AFAIK diagnostics like that are not possible because Walter
doesn't want to implement full blown dataflow analysis in the
compiler since it will slow down the compilation speed of dmd
