I think you can simplify the code by reducing `CoarseParser` down to a
language-specific regular expression with "standard" named groups for the
payload and markup.
I'd also recommend not using an `enum` for `Language` to leave open the
possibility of easily/dynamically adding support for additional languages.

The idea of a `Language` object is good, but using an `enum` precludes easy
extensibility.

I'm surprised/disappointed that this may be necessary, although I accept there
is a notable difference between "whole-line comments" and "end-of-line
comments". Is it possible to reduce `CoarseParser` down to a language-specific
regular expression with named groups for the payload and markup, such that the
regular expression could be a property of the `Language` object?

Given that matchers are lightweight objects, what is the benefit of using a
pre-allocated matcher and `reset` as compared to a temporary `Matcher` object?
Is it just style, or is there something more?

Suggest using named groups

move before imports

Suggest moving to SnippetTester (suggested in dependent PR)

Just curious: why force this?
