Hello,
A question about the syntax: would there be a problem if we made the
'deriving' declaration look like an instance? Then we would not need
the special identifier 'for', and also we have a more standard looking
notation. I am thinking something like:
deriving Show SomeType
deriving Eq (AnotherType a)
-Iavor

Yes. There is even a "for" function somewhere in the libraries (or was
it the testsuite, can't remeber), which tripped up one of my early
versions, before I had remembered to make "for" as a special ID in the
parser.

Sure. It seems that I have to be on the committee to write to the Wiki.
Can I join it?
