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.

From bug 8035:
----
import std.regex, std.string;

void main() {
    split(s"hello", regex("[ \t,.;:?]+"));
}
----

This is a TDPL issue at p.18 (http://erdani.com/tdpl/errata/).
