There was a problem hiding this comment.
std::optional does support comparison without dereferencing (see (26) in https://en.cppreference.com/w/cpp/utility/optional/operator_cmp) but your variant is better as operator< would repeat if (opt) check you already (rightly) did.

…onal 4830f49 qt: Refactor open date range to use std::optional (João Barbosa) Pull request description: Use `std::nullopt` for open date range instead of `TransactionFilterProxy::MIN_DATE` and `TransactionFilterProxy::MAX_DATE`. ACKs for top commit: hebasto: re-ACK 4830f49, only missed header included since my [previous](bitcoin-core/gui#354 (review)) review. Talkless: tACK 4830f49, tested on Debian Sid, filtering seems to work as expected.
