Is there an official example of using react-intl with class components?

The docs say:

injectIntl HOC: In class-based React components, you can wrap them with the injectIntl HOC and intl should be available as a prop.

But the section on injectIntl HOC only uses a functional component.

I'm attempting to migrate my class component-based app to use react-intl, and I'm able to get it working, but there were a couple of surprises:

1. For components used in the same file, I have to rename my classes, e.g. Foo becomes FooBase
2. Probably user error somewhere, but class components that already had props are giving me red squigglies when instantiated via JSX in VS Code after wrapping them in injectIntl -- I'm intentionally omitting the error details here because I'm fairly certain I'm just doing something dumb -- but I don't have a "known good" example to compare against (all the examples I see are for trivial components without other props, and I searched for "class" in the examples/ directory and found no hits)

Explicitly passing intl as props works fine for me, but I had assumed using injectIntl was best practice.
