Bug 7955 – Nested function error in sort with lambda template but not with a lambda

import std.algorithm: sort; int foo(int n)() { sort!((a, b) => true)([1]); //sort!((int a, int b) => true)([1]); foo!1(); return 0; } void main() { foo!0(); } DMD 2.059 shows: ...\dmd2\src\phobos\std\algorithm.d(6781): Error: function test.foo!(0).foo.sort!(__lambda3,cast(SwapStrategy)0,int[]).sort is a nested function and cannot be accessed from test.foo!(1).foo The version that uses the lambda instead of a lambda template compiles correctly (then crashes at a runtime because the sort function is stupid).

Reduced testcase: --- void f(alias fun)() { } void g(T)() { f!(a => a)(); } void main() { g!int(); g!long(); } --- Error: function main.g!(int).g.f!(__lambda2).f is a nested function and cannot be accessed from main.g!(long).g Workaround: explicitly define lambda type: `(int a) => a`.

Like Issue 7917 it compiles fine now. Then crashes at a runtime because of infinite recursion. Please open a new issue is there is a problem with `sort`.
