...LiquidHaskell (LH) refines Haskell's types with logical predicates that let you enforce important properties at compile time. LH warns you that head is not total as it is missing the case for [] and checks that it is total on NonEmpty lists. The input contract propagates to uses of head which are verified by ensuring the arguments are NonEmpty. LH lets you avoid off-by-one errors that can lead to crashes or buffer overflows. Dependent contracts let you specify, e.g. that dotProduct requires equal-sized vectors. LH checks that functions terminate and so warns about the infinite recursion due to the missing case in fib.
