This is not true. If it's in language, you have to understand it to be
able to use the language. Nobody writes code in vacuum - there are
libraries, communities, teams, best practices, tutorials, etc. So if
(hypothetically) you want to introduce algebraic types in PHP, then
since that moment you can not really be a PHP programmer if you don't
understand algebraic types. Otherwise you would not be able to
communicate with the rest of the community, understand and use code
written by others, contribute to projects, etc.
I agree. This is an important point. I should include it in my RFC[1]
that argues pro nullable return but contra nullable params or unions.
May I copy-paste?
