This error message was a consequence of details of an optimization rule 
in the compiler.  Currently, all first-class functions must be 
eliminated from server-side code before compilation ends; the code 
generation scheme just doesn't have any way of dealing with them.  Small 
changes in optimizations can affect whether certain first-class 
functions survive, and every piece of [transaction] code effectively 
becomes such a function.

I've pushed a changeset that fixes the problem for your code, though it 
might break something else.  A different, more fundamental way of 
handling this issue is on my to-do list for the next big Ur/Web rewrite. ;)
