With GHC-HEAD, it compiles no longer(!):
[1 of 2] Compiling AppendCallStack ( AppendCallStack.hs, AppendCallStack.o )
AppendCallStack.hs:6:1: error: • Illegal implicit parameter ‘?callStack::CallStack’ • In the type synonym declaration for ‘AppendsCallStack’
So Richard, does it do what you want with GHC-7.10? And given that GHC HEAD rejects it, was 7.10 wrong or is there a bug in HEAD?
Eek. That's a bug. :( Richard
