=== Guard Clauses === Guard clauses further enhance the power of function clauses by allowing additional conditions to be specified for pattern matching. Guard clauses are specified after the pattern matching arguments and are enclosed in the `when` keyword. Here is an example: ```elixir defmodule Math do def divide(a, b) when b != 0 do a / b end def divide(_, 0) do {:error, "Divide by zero"} end end ``` In the above code, we define the `divide` function with two clauses. The first clause handles normal division, but only when the second argument is not zero. The second clause handles the specific case of dividing by zero, returning an error tuple.
