why cannot spawn function defined in unittest block {}?
put the code from: https://tour.dlang.org/tour/en/multithreading/synchronization-sharing in file, and put unittest block from safePrint() to main() as here: https://github.com/mingwugmail/dlang_tour/blob/master/spawn_in_unittest.d#L33 - $ dmd -unittest spawn_in_unittest.d spawn_in_unittest.d(87): Error: template std.concurrency.spawn cannot deduce function from argument types !()(void delegate(shared(SafeQueue!int) queue, shared(int)* queueCounter) @system, shared(SafeQueue!int), shared(int)*), candidates are: /usr/include/dmd/phobos/std/concurrency.d(460):spawn(F, T...)(F fn, T args) with F = void delegate(shared(SafeQueue!int), shared(int)*) @system, T = (shared(SafeQueue!int), shared(int)*) must satisfy the following constraint: isSpawnable!(F, T) spawn_in_unittest.d(88): Error: template std.concurrency.spawn cannot deduce function from argument types !()(void delegate(Tid owner, shared(SafeQueue!int) queue, shared(int)* queueCounter) @system, Tid, shared(SafeQueue!int), shared(int)*), candidates are: /usr/include/dmd/phobos/std/concurrency.d(460):spawn(F, T...)(F fn, T args) with F = void delegate(Tid, shared(SafeQueue!int), shared(int)*) @system, T = (Tid, shared(SafeQueue!int), shared(int)*) must satisfy the following constraint: isSpawnable!(F, T) - spawn in unitest: why this compiler error? confusing message

the function defined in unittest become a delegate? how to work-around this?
