[Lucian Danescu]

Hello!
​

Since my last update I focused on the final touches for a few pr 
that were pending
for some time, and managed to complete the work for the following 
visitors which are now merged:
  - 
[assert_without_message](https://github.com/Dlang-UPB/D-scanner/pull/50)
  - 
[auto_ref_assignment](https://github.com/Dlang-UPB/D-scanner/pull/51)
  - 
[builtin_property_names](https://github.com/Dlang-UPB/D-scanner/pull/52)
  - 
[opequals_without_tohash](https://github.com/Dlang-UPB/D-scanner/pull/53)
  - 
[logic_precedence](https://github.com/Dlang-UPB/D-scanner/pull/54)

I also implemented a couple of new visitors, which are waiting 
for an the approval from my mentor:
  - 
[exception_check](https://github.com/Dlang-UPB/D-scanner/pull/55)
  - 
[static_if_else](https://github.com/Dlang-UPB/D-scanner/pull/56)
