Bug 21663 – std.concurrency.receiveOnly doesn't work with tuples

See sample code: int main() { import std.concurrency; receiveOnly!(string, bool, bool); return 0; } This works in 2.094 (and the application from which it is extracted also works) but fails with the following error in 2.095: /usr/include/dmd/phobos/std/concurrency.d(806): Error: template instance isAssignable!(string, bool, bool) does not match template declaration isAssignable(Lhs, Rhs = Lhs) test.d(3): Error: template instance std.concurrency.receiveOnly!(string, bool, bool) error instantiating I have no idea what this error really mean if I'm honest.

Looks like `recieveOnly` is using `isAssignable!T` where it should be using `allSatisfy!(isAssignable, T)`: https://github.com/dlang/phobos/blob/v2.095.1/std/concurrency.d#L806
