          Issue ID: 13884
           Summary: No error line number with std.array.array of range of
                    type tuples
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Keywords: diagnostic
          Severity: normal
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: bearophile_hugs eml.cc

This is wrong code:

import std.array: array;
import std.algorithm: map;
struct Foo { int x; }
void main() {
    [Foo(1)].map!(t => t.tupleof).array;
}


Dmd 2.067alpha shows an error without line number:


Error: no size for type (int)
temp.d(5,19): Error: functions cannot return a tuple
...\dmd2\src\phobos\std\algorithm.d(450,16):        instantiated from here:
MapResult!(__lambda1, Foo[])
temp.d(5,13):        instantiated from here: map!(Foo[])
