The import all is discouraged. I don't have any solid evidence, but I strongly suspect that the above would not happen for D. It seems to me that the cost benefit balance falls in favor of just importing everything. I suspect that it's similar to how in dynamic languages there is a much stronger argument for TDD because, IIRC, python is a dynamic language and D is not. > And when people what to use the unqualified import syntax, adding two chars > ".*" is not going to cost them much. Not my point.

Most of the time using Phobos, I want to have most of or none of a module available (even if I don't use some of it). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
