    Improve heap-allocation by adding explicit type signatures.
    
    When a local 'go' function is using methods from Ord dictionary,
    this dictionary is heap-allocated at the entry to the outer function.
    If it is given explicit type mentioning the Ord class, the dictionary is
    passed on the stack, decreasing heap allocation.
