eb48a035e7 fix corner case in unused (#1718) 
When fixing catch-related issue in #1715, it tries to optimise for duplicate definitions but did not take anonymous functions into account.

Remove such optimisation for now and we can cover this as a more general rule later.

a30092e20f fix invalid AST_For.init (#1657)
