[isabelle-dev] Odd name space problem in quickcheck or codegen (due to change in typedef)

Maybe a guess in the blue, but here is what grep tells me:

~$ grep base_name ~/isabelle/src/HOL/Tools/ -r | grep Quick
/Users/traytel/isabelle/src/HOL/Tools//Quickcheck/abstract_generators.ML:    val name = Long_Name.base_name tyco

I have not investigated further.
