Effect.matchCause

失敗理由を単なるErrorではなく、Cause (effect)として扱う

通常の失敗とバグ（想定外の例外）を分けて扱いたいときに使う

例

code:ts

const program = Effect.matchCause(effect, {

onSuccess: (value) => Success: ${value},

onFailure: (cause) => {

switch (cause._tag) {

case "Die": return Defect: ${cause.defect}

case "Fail": return Error: ${cause.error.message}

case "Interrupt": return ${cause.fiberId} was interrupted

}

})
