Bug 3506 – [module] Imports should be valid at any scope

Imports should be valid at any scope, like classes, structs, and functions. This is specially useful for unit tests for example, currently this idiom is needed: version (unittest) import foo; unittest { foo.bar(); } It would be much nicer to be able to just write: unittest { import foo; foo.bar(); } This brings more locality to the code. This limitation is like C's (pre C99) inability to add variable declarations after the first statement. It easier to refactor code this way too, if I move the unittest (function, class or whatever) to another file, my imports are moved too without any further work, now I have to track all the import and remove/add appropriately.

cat > foo.d << CODE void bar() {} CODE cat > ut.d << CODE unittest { import foo; foo.bar(); } CODE dmd -c -unittest ut.d
