[Haskell-cafe] generalize RecordPuns and RecordWildCards to work with qualified names?

[Simon Peyton-Jones]

Can you give a concrete program to illustrate your point, please?  I'm not getting it.

| Record punning is not all that useful with qualified module names.  If
| I write '(M.Record { M.rec_x })' it says " Qualified variable in
| pattern" and if I write '(M.Record { rec_x })' it says 'Not in scope:
| `rec_x''.  Could it be this extension be further extended slightly so
| that 'f (M.Record { M.rec_x })' will desugar to 'f (M.Record { M.rec_x
| = rec_x })'?
| 
| Similarly, RecordWildCards could support this too.
| 
| It seems simple and useful to me... am I missing anything fatally
| problematic about this?  Would anyone else use it?
