2141	Internal error on invalid record update	rl	igloo	"A silly function:

{{{
foo :: () -> ()
foo x = x { foo = 1 }
}}}

6.8.2 says:

{{{
GHC internal error: `foo' is not in scope
In the expression: x {foo = 1}
In the definition of `foo': foo x = x {foo = 1}
}}}

HEAD's message is a bit more illuminating:

{{{
GHC internal error: `foo' is not in scope during type checking, but it passed the renamer
tcg_type_env of environment: []
In the expression: x {foo = 1}
In the definition of `foo': foo x = x {foo = 1}
}}}
