Maybe it's all just marketing. But sometimes marketing is also a form of education, it teaches people a new way to do something, or why they should care about something. Another possibity is that maybe the ecosystem around a language is changed, today more people use an IDE (especially people that don't use C/C++), and if you are using an IDE then maybe it is an useful feature. Probably reality is a mix of those different possibilities. > Clang did have a nice idea with the spelling corrector.

I presume some people have said it was a "waste of time" because currently there are more important issues/bugs in DMD. In the meantime I have underlined a second small idea from Clang that I think will be useful to implement in D/DMD too, the use of "aka", this is an example from Clang: t.c:13:9: error: member reference base type 'pid_t' (aka 'int') is not a structure or union This is a wrong D2 program: void main() { alias int Foo; Foo f; f = f.x; } DMD 2.049 prints: test.d(4): Error: no property 'x' for type 'int' But a more useful error message may be: test.d(4): Error: no property 'x' for type 'Foo' (aka 'int') In a tiny program like that the difference doesn't show much, but as programs get bigger, and alias is more far from its usage, it will be useful.
