[MacRuby-devel] Invoking a block in MacRuby, instantiated in Objective-C

There's plenty of documentation showing how one can use Proc objects to invoke Objective-C methods that accept block parameters, but I can't find any way to invoke an Objective-C block from within a Ruby method.
Without thinking I had assumed they'd be mapped to a Proc-like object, which I could invoke with #call:
def performOperation(operation, success:success_callback, error:error_callback)
result = "..."
But I get an error: undefined method `call' for #<__NSAutoBlock__:0x2006b6560>
