Given how long http://hackage.haskell.org/trac/ghc/wiki/ExplicitCallStack has been under discussion, it is probably time to provide a short-term workaround in GHC, just a token to be replaced by the current source location.
This would be the best solution. Although -fno-ignore-asserts is acceptable till I do not need asserts for what they are actually supposed to be used for. The second solution requires QuasiQuotes, so I do not know. If I would want to compile with a different compiler it would break. If srcloc can be defined as a simple token (not requiring special extensions at places where it is used) then I could define it to an empty string in some low level module if trying to compile with a different haskell compiler which does not know srcloc. Thanks for the tips, Peter.
