[Swift-devel] Attempted to close nonexistent channel buffers

[Ben Clifford]

Recently I've seen this message:

> Execution failed:
>        Attempted to close nonexistent channel buffers

on occasion, when a procedure is invoked with the wrong number of 
parameters.

I hope that this will get caught at compile time later on when some more 
compile-time type-checking work is done; but here's a note on it for the 
archives and Google.
