This is wrong code because it doesn't import std.typecons.tuple:


import std.range: iota;
import std.algorithm: map;
void main() {
    iota(1).map!(x => tuple(x));
}



DMD 2.063alpha gives:

Assertion failure: 'type->ty != Tstruct || ((TypeStruct *)type)->sym == this'
on line 668 in file 'struct.c'

The error message is now:

Assertion failure: 'type->ty != Tstruct || ((TypeStruct *)type)->sym == this'
on line 722 in file 'struct.c'

Raising importance to major because I am hitting this problem all the time.

After this change:

https://github.com/D-Programming-Language/dmd/commit/dec31f42148fe14a24250592ee21e376ac1d8a88


Now the code shown above gives no ICE:

test.d(4): Error: undefined identifier tuple
...\dmd2\src\phobos\std\algorithm.d(404): Error: template instance
test.main.__lambda2!(int) error instantiating
...\dmd2\src\phobos\std\algorithm.d(390):        instantiated from here:
MapResult!(__lambda2, Result)
test.d(4):        instantiated from here: map!(Result)
...\dmd2\src\phobos\std\algorithm.d(390): Error: template instance
test.main.MapResult!(__lambda2, Result) error instantiating
test.d(4):        instantiated from here: map!(Result)
test.d(4): Error: template instance test.main.map!(__lambda2).map!(Result)
error instantiating

So do you want me to close down this issue?
