Re: [Haskell-cafe] an idea for modifiyng data/newtype syntax: use `::=` instead of `=`

type -> alias data -> data newtype -> newalias or newdata? `type` keyword was really confusing for me at the beginning, also this confusion brought another one about `newtype` keyword. сб, 8 авг. 2015 г. в 22:28, Hilco Wijbenga :

if we're at it ;), then please change it to:

I wholeheartedly agree with replacing the current "type" with "alias", the current "type" is just flat out wrong: it does *not* create a type. This should be very simple to do too: introduce "alias" as a new keyword and deprecate "type". No existing code would be affected.

I'm on the fence about "type" instead of "data", though. "data" clearly conveys the meaning that we are talking about data only, not functions on that data (as in OOP). (Well, data constructors are functions too.) Then again, as soon as you add "deriving", you *are* defining functions on that data. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/haskell-cafe
