I'm struggling to understand this.

I want a list of MerchantRecord -> String?

I've got the following code.

private fun toTree(inputRecords: List<MerchantRecord>) {
		val byMerchant: (MerchantRecord) -> String? = { it.merchantName }
		val byAccount: (MerchantRecord) -> String? = { it.accountName }

		val groupings = listOf({ it.masterMerchantName }, { it.portfolio }, byMerchant, byAccount)
		toTree(inputRecords, groupings)
	}

And In intellij I can refactor inline. ByAccount or byMerchant

however as soon as I refactor the last entry it complains.
