No, it was just a little more convenient, because the with_ctx function also 
cleaned up the context and logger after use, so you won't be able to forget 
this. I have now taken Dave's advise and wrapped the ctx and logger pointers in 
custom block with "finalize" (GC) functions, so this became less useful. I have 
remove this patch in my v2 series.
