http://d.puremagic.com/issues/show_bug.cgi?id=3507 Summary: [module] Flag unused imports to avoid unnecessary dependencies Product: D Version: future Platform: Other OS/Version: All Status: NEW Keywords: diagnostic Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: llucax gmail.com PST --- Dependencies makes compile time increase in large projects and have other bad impact in the code. An import might even execute code (module ctors), which can make the program slower at *run-time* unnecessarily if the module is not really used. I think unused import should trigger *at least* an optional warning (with -w or something) to aid the programmer in detecting unused modules. A way to tell the compiler that an unused module is OK should be provided (in case we need the module ctor to run), a possible syntax is a special renamed import: import void = foo.bar.baz; A special selective import can do the job too: import foo.bar.baz: void; -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
