test.d:
module test;
public:
import std.string;
import std.algorithm;

main.d:
import test;
import std.string;
void main(){  auto a=" af ".strip;}

dmd -c -o- main.d
main.d(4): Error: test.strip at test.d conflicts with std.string.strip(C)(C[]
str) if (isSomeChar!C) at phobos/std/string.d(1268)

Remove any of the 4 imports and it'll compile.
Also, there's no line number in 'at test.d'

actually this is a regression (worked in 2.063)

Introduced in https://github.com/D-Programming-Language/phobos/pull/1311, but
this really looks like a compiler bug in the vein of 314.

This is not a compiler bug. It has nothing to do with 314.

The problem is that 'strip' is defined in both std.string and std.algorithm.

This is a compiler bug because this program doesn't compile (as is expected):

/////// test.d //////
import std.algorithm;

void main()
{
    " af ".strip;
}
/////////////////////

And this program compiles (as it should):

/////// test.d //////
import std.algorithm;
import std.string;

void main()
{
    " af ".strip;
}
/////////////////////

Note that the above program differs from OP's only in how imports are
"funneled".

Therefore, there should be no conflict, because out of std.algorithm.strip and
std.string.strip, only one will work with those parameters.

 This is not a compiler bug. It has nothing to do with 314.
 The problem is that 'strip' is defined in both std.string and std.algorithm.


This is a compiler bug on cross-module overload set handling. It's not directly
related to issue 313 & 314.


 test.d:
 module test;
 public:
 import std.string;
 import std.algorithm;


In test.d, 'strip' is a cross module overload set (CMOS) of 'std.string.strip'
and 'std.algorithm.strip'.


 main.d:
 import test;
 import std.string;
 void main(){  auto a=" af ".strip;}


In main.d, 'strip' is a CMOS of the CMOS in test.d and 'std.stding.strip'.
So, the newly created CMOS should be merged to the set [std.string.strip,
std.algorithm.strip]. But currently OverloadSet and template cannot be merged
into one OverloadSet object in ScopeDsymbol::search.
