Error in execCallbacks(timeoutSecs, all, loop$id) : Evaluation error: unused argument (0) #125

Any hints what can cause this? The callback I pass to later actually called and then I such traceback:

Error in execCallbacks(timeoutSecs, all, loop$id) : Evaluation error: unused argument (0). 4. stop(structure(list(message = "Evaluation error: unused argument (0).", call = execCallbacks(timeoutSecs, all, loop$id), cppstack = structure(list( file = "", line = -1L, stack = c("1 later.so 0x000000010dbcd1df _ZN4Rcpp9exceptionC2EPKcb + 207", "2 later.so 0x000000010dbd0e3e _ZNK8Callback14invoke_wrappedEv + 590", ... 3. execCallbacks(timeoutSecs, all, loop$id) 2. later::run_now(timeoutSecs = 0.1, all = FALSE, loop = loop) at NsqConsumer.R#85 1. consumer$start(10)

Ah, sorry that was a bug in my code. But error from later made me struggle to understand what happened.

Hopefully after #108 is addressed, it'll be easier to debug issues like this.
