What I (so vaguely) remember was a compile error, for some reuse of
an identifier where GHC permitted it. I suppose you're right, anyway,
probably something else - maybe unambiguous nested shadowing?
let x = t + 1 in
let y = x in
let x = y + 1 in x
GHC allows this, and of course there's no recursion.
