The negation of this is what gets added when T[L,U] is added to probability function foo.
Then we'd use those for censoring and truncation instead of the expression the right, which we're using now. It should be done with a log-sum-exp type operation. Even a utility implementation that just used Stan's existing log_diff_exp function would be useful.

It'd be useful for both efficiency and ease of notation if we had a function defined by:
