Congratulations! You've just run into issue 5710 [1], one of D's
most annoying known bugs.
[1]: https://issues.dlang.org/show_bug.cgi?id=5710
The snippet above compiles with the reduce function from
std.algorithm.

Why the interface difference between std.algorithm's reduce and
taskPool.reduce ?
std.algorithm.reduce is a free function, so it can accept
delegates as template parameters. taskPool.reduce is a member
function, so it can't.
