    warning: missing parentheses for expression following "do:" keyword. Parentheses are required to solve ambiguity inside keywords.

    This error happens when you have function calls without parentheses inside keywords. For example:

        function(arg, one: nested_call a, b, c)
        function(arg, one: if expr, do: :this, else: :that)

    In the examples above, we don't know if the arguments "b" and "c" apply to the function "function" or "nested_call". Or if the keywords "do" and "else" apply to the function "function" or "if". You can solve this by explicitly adding parentheses:

        function(arg, one: if(expr, do: :this, else: :that))
        function(arg, one: nested_call(a, b, c))

    Ambiguity found at:
    │
  7 │       String.equivalent?(c, "<") -> if si < ti, do: IO.puts "YES", else: IO.puts "NO"
    │       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
