 Possibly related here is:

 It says that `TerminateProcess` is async and you have to wait for the
 process to really terminate before file locks are released. Of course here
 we think we are waiting for processes to terminate but perhaps we should
 double check how we're doing that.

 Hmm, seems we do call `WaitForSingleObject` on the process handle.

 When building a simple program that is built using -dynamic, the resulting
 executable fails with the following error:

 /Users/ian/zz64/ghc-7.4.1/libffi/build/inst/lib/libffi.5.dylib
   Referenced from: /usr/local/lib/ghc-7.4.1/libHSrts-ghc7.4.1.dylib
   Reason: image not found
 [1]    90849 trace trap

 The workaround in this case is to execute the following two commands:

 otool -id /usr/local/lib/ghc-7.4.1/libffi.dylib
 /usr/local/lib/ghc-7.4.1/libffi.dylib

 install_name_tool /usr/local/lib/ghc-7.4.1/libHSrts-ghc7.4.1.dylib -change
 /Users/ian/zz64/ghc-7.4.1/libffi/build/inst/lib/libffi.5.dylib
 /usr/local/lib/ghc-7.4.1/libffi.dylib

 which is to say that the library  at /usr/local/lib/ghc-7.4.1/libffi.dylib

 All of the installed libraries are placed in
 /Library/Frameworks/GHC.framework/Versions/7.4.1-x86_64/usr/lib/ghc-7.4.1
 by the installation package.

 However, all of the dylib files report an otool -D of the form
 /usr/local/lib/ghc-7.4.1/...

 The workaround is to create a link from /usr/local/lib/ghc-7.4.1 to
 /Library/Frameworks/GHC.framework/Versions/7.4.1-x86_64/usr/lib/ghc-7.4.1

 However, the installer should either create this link, or (better) invoke
 otool -id as part of the installation process and set the correct dylib
 path for all the dylibs.

 You're right, `safeShowException` can be used regardless. I simplified the

Comment:

 The attached patch adds a "qualified quasi quote" token to the lexer, and
 the corresponding production to the parser.
