import std.algorithm; import std.array; class S { } class T { @property bar() inout { return _bar; } S _bar; } string fun() { auto ts = [new const T]; ts.map!(t => t.bar).array; } ---------------------------- /usr/include/d/4.9/std/conv.d:3914: error: static assert "S cannot be emplaced from a const(S)." /usr/include/d/4.9/std/array.d:49: note: instantiated from here: emplace!(S, const(S)) src/array.d:13: note: instantiated from here: array!(MapResult!(__lambda1, const(T)[]))

I've been advised that this works with 2.068. I'll go and upgrade now. Sorry for the noise.

Scratch that last comment. I misunderstood.

Aside from the fact, that fun() does not return a string, this seems to work. Any reasons not to close this?

Works for me too. Please reopen if the bug still exists.
