Lets bike shed!
For some time, functions with names like fooIfExists and ensureFoo have been
bothering me. I find both names kind of opaque and unpleasant. Here’s an
example:
StyleResolver* styleResolverIfExists();
StyleResolver* ensureStyleResolver()
What do you think of these names instead?
StyleResolver* optionalStyleResolver();
StyleResolver& requiredStyleResolver();
I like them better. Note also that I think the requiredStyleResolver function
should return a reference so nobody is tempted to do null checks. It seems like
the C++ community likes the name optional for this concept; isn’t there some
kind of std::optional template?
