I get Patterns match(es) are overlapped.
You can't use arbitrary expressions in patterns; any name (not a data
constructor) used in one creates a new lambda binding (shadowing any
existing binding) which receives the value at that point in the
pattern. So

captures the value of name in a new binding c_a.
