Thanks for the feedback. Could you comment a bit more a provide
a link to explain why the record system is broken?
Do you have the uniqueness of selector names in mind?
Currently, we plan to provide only syntactic sugar for entities
which we usually implement by hand. Maybe we can avoid the
problems in Haskell by restricting the generality of the
record system. On the other hand, there seems no better alternative
up to now, so record syntax is better than nothing...

I mean the name is obscure for meaningful functions
or pattern variables so that it is not used in existing programs.
However, the name x_ is reasonable to denote an anonymous free
variable. Or any better suggestion for a compact name?
Best regards,
Michael
