Unused import detection tool for D

Unused import tool for D

This tool identifies unused top-level imports. It uses dmd as a library, therefore it performs full semantic analysis before checking whether an import used or not. As such, it is currently very limited:

• it only identifies unused top-level imports.
• it does not work for selective or renamed imports.
• aliases are eagerly substituted so we cannot know if imported_module_a.var is actually a direct use of var or whether alias imported_module_b.alias_to_var was used.
• enums are eagerly substituted with their correspoding integer value, so you cannot know whether 3 was actually imported_module.Enum_decl.Three or the literal 3.

To use the tool:

chmoad a+x unused_import.d
./unused_import.d
