No, D packages are not closed; anyone can add new modules to them at any time.

You can detect templates with `static if (__traits(isTemplate, mixin(sym)))`, but in general there is no way to know whether it's a template function, because in order to introspect it you have to instantiate it first, but there is no general way to automatically instantiate a template. Its arguments can be subject to arbitrary signature constraints, and it may in theory be a template function only for a subset of its possible arguments, so there isn't any good way to automatically deduce what template arguments would instantiate into a valid function. You can only get at a template function if you already have an instantiation of it. T -- Guns don't kill people. Bullets do. |
