What's the main goal with this proposal? Is it to introduce DCDs
into the language or is it to clean up some warts of the local
import pattern, i.e.:
int doSomething(T)(T t) //std.range is lazily imported but
{ //can't be used in the signature
import std.range;
//...
}
struct Test(R) //Ditto
{
import std.algorithm;
//etc...
}
I'm assuming it's the former, or there wouldn't be any talk about
introducing any new syntax. Imports would just be made completely
lazy and we wouldn't have to change the language at all
otherwise. So other than the fact that you can move the
declaration anywhere without breaking it due to missing imports,
are the advantages that DCDs provide really worth it enough to
introduce yet another clause that can be put on any declaration?
Especially when we have another solution (lazy imports) that does
exactly what you want but excludes the DCD aspect?
