[Haskell-cafe] Re: syscall, sigpause and EINTR on Mac OSX

[Joel Reymont]

Oh, right. It does not apply in my case, though, so I thought it was  
safe.

I'm not sure what the proper Haskell wording is to explain but it  
seems like the type system catches if a user of the library tries to  
use two different a's (Child a) and complains. Exactly what I need as  
access to children is hidden within my code.
