Selective import is quite rotten. Continuing where I left with 8667 I've found
another issue now with public selective import:
Again given a few simple modules:
module m;
void split(T)(T k)
if(is(T : string))
{
}
module m2;
void split(T)(T k)
if(is(T : int))
{
}
//drop in another one to pull split from m2
module m3;
public import m2: split;
//and the one to call them...
import m;
import m3; //replace with m2 to make it work
void main(){
split("abc");
split(123);
}
Compiling this all together yeilds an output that suggest that 2 templates are
in conflict:
tryit.d(5): Error: m.split(T) if (is(T : string)) at m.d(3) conflicts with
m3.sp
lit at m3.d(3)
tryit.d(6): Error: template m.split does not match any function template
declara
tion
tryit.d(6): Error: template m.split(T) if (is(T : string)) cannot deduce
templat
e function from argument types !()(int)
DMD 2.060 been there since at least 2.056.
