Bug 15558 – std.parallelism giving inscrutable error messages

struct Host { @disable this(this); } void main() { uint[] arr; import std.parallelism; auto hostmap = taskPool.map!(function Host(uint a) { return Host.init; })(arr); } Gives me: /Library/D/dmd/src/phobos/std/parallelism.d(1677): Error: cannot interpret (uint[], ulong, Host[]) at compile time /Library/D/dmd/src/phobos/std/parallelism.d(1677): Error: static assert __error /Library/D/dmd/src/phobos/std/parallelism.d(1996): instantiated from here: amap!(uint[], ulong, Host[]) fail.d(11): instantiated from here: map!(uint[]) Turns out the @disable this(this); is key in triggering the error.
