Weight-based random sampling

Multiple guards in Elixir

The only difference between case and function heads is the exception generated when no clause matches - CaseClauseError vs FunctionClauseError - in internal passes the only thing the compiler works with is case, everything else is lowered into that.

Perhaps naively I think it’s better to make the condition explicit in say a case statement,

Pattern matching‡ is the conditional construct - the case expression is just one way of utilizing it.

‡ Not to be confused with destructuring:

• Kernel.destructure/2
• JavaScript destructuring assignment
