Which package?
react-intl

Is your feature request related to a problem? Please describe.
I regularly end up writing the exact same lines of code

b: (...chunks) => <b>{chunks}</b>,
p: (...chunks) => <p>{chunks}</p>,

Describe the solution you'd like
I'd like to see an abstraction on top of formatMessage (or built in) that takes care of a standard set of html tags.

It might be make sense automatically convert tags to functions like the ones I listed above and then allow those to be overridden using the current interface.
