in thread Recursively walk a hash to get to an element

The reason of the error is that reduce uses a prototype not yet seen when the return statement is compiled. It's therefore interpreted as indirect object syntax (method { STATEMENTS } LIST), being do { STATEMENTS }->method(LIST) with direct syntax. The way to fix this is to call &reduce like List::Util::reduce(sub { ... }, LIST).

See perltoc if you don't know which perldoc to read!
