A proposal for extending std::optional with convenience functions that allow you to skip a whole lot of if has_value() boilerplate and do things like:

auto result = some_optional
    .transform(function1)
    .transform(function2);

See the proposal for more details.

Contents:

• The proposal itself, proposal.md
• TODO
• Example implementation in a single header file, optional_ext.h
• A demonstration, demo.cpp
• Unit tests, optional_ext_test.cpp (Written in Catch 2.)
