I'm not a lawyer, so can't offer legal advice (and certainly I'm not qualified to say whether the extensible exceptions code would be considered to be derived from the more primitive exceptions API in the Haskell 98 report). But I wonder why it matters whether the extensible-exceptions code is under that licence, when anything using it presumably also uses base or haskell98, which both have the same licence? Unless perhaps you're porting it to a different language or something? > 2) If the derived code was compiled with the following language in the > license: "modified version is clearly presented as such, and that it does > not claim to be a definition of the Haskell 98 Language"? > Same questions about the "Haskell Foreign..." license. I didn't follow that. Did you mean "complies with" rather than "was compiled with"? If so, I don't think that anyone would say that extensible-exceptions claims to be a definition of the Haskell 98 Language (but again, I'm not a lawyer etc). > I'm attaching below excerpts from your license for your convenience. > > Also I'm copying you (see below) on the similar communication with Milan > Straka on Haskell_Containers license.
