Hi all,
Our own Jaro Reinders, based on a proposal originally by Artyom Kuznetsov, proposes to introduce `-Wpuns` and `-Wpun-bindings`, to warn users when the same name appears in the term namespace and type namespace:
These warnings would not be enabled by default, but would bring us a step forward on the path outlined by the accepted proposal #378 (Support the design for dependent types,
https://github.com/ghc-proposals/ghc-proposals/pull/378), by supporting writing code in a way that plays well with the principles described in that proposal (i.e. the lexical scoping principle and syntactic unification principle).
They are also a good match for the recently introduced `-XNoListTuplePuns`, which already lets users avoid puns for some builtin types. Any users of `-XNoListTuplePuns` will likely want something along the lines of this proposal.
I left some comments on the github thread but I think they are small enough that they don't have to prevent us from voting on it.
I recommend we accept.
Please indicate whether you wish to accept this proposal.
Jakob
